Adsorption of four pharmaceuticals and personal care products (PPCPs) by activated carbon (AC) before and after oxidative modification with ammonium persulfate (APS) at different concentrations was studied. The results indicated that this method with novel RAM-SPE adsorbents is sensitive and convenient. Also, synthetic adsorbents (carbon nanotubes, graphene, functionalized organo-silicates and silicas) for the removal of organic compounds from aqueous effluents will be employed. Additionally, a calcined hydrotalcite has been used to adsorb Bentazon. Hence biochar has been widely used in the field of soil remediation [15] and wastewater treatment [16,17]. Bisphenol A (BPA) is a known endocrine disruptor that is acutely toxic to the living organisms. Adsorption of typical pharmaceuticals and personal care products (PPCPs) (such as naproxen, ibuprofen and oxybenzone) from aqueous solutions was studied by using the highly porous metal-organic framework (MOF) MIL-101 with and without functionalization. The conventional primary and secondary water treatment plants do not remove or degrade these toxic pollutants efficiently and hence need cost effective tertiary treatment method. Adsorption study showed that the adsorption capacity of CAC towards PRC was less affected by solution pH value (2.0–10), and ionic strength (0–1.0 M NaCl), and different water matrixes (distilled water, tap water, seawater, water treatment plant, groundwater, and beauty salon). About the applicability of the ACs for treating simulated effluents, the tucumã seed activated carbon showed an excellent outcome in the treatment of simulated effluents, evidencing its high-efficiency for phenolic compound adsorption. use different type of organic dyes, heavy metals and organic phenols and expose to the environment. M-HPD 100 has good regeneration capacity after 6 times regeneration. Different analytical techniques were used to characterize the activated carbon. Various adsorbents materials have been tested such as biomass 10, Dyes, phenols, amines and other organic compounds are largely employed in the industry such as textiles, paper, polymers, pesticides, pharmaceuticals, explosives, oil additives, rubber, steel, etc, Current water desalination techniques require high energy input and costly membranes. Several experiments were carried out to study the efficiency of mesoporous activated carbons (Meso-AC) and as-synthetized multi-walled carbon nanotubes (intermittently MWCNTs or CNTs) to remove two pharmaceutically active compounds (PhACs), Carbamazepine (CZ) and Dorzolamide (DA), from artificially contaminated waters. Among them, sorption is one of the most preferred mainly because it is economically viable whereas the other practices are much more expensive, ... Adsorption of ECs onto the adsorbents is a way to separate the ECs from the water matrix while it presents no significant treatment and reusability of adsorbents is a challenge. USA.gov.

We found that the adsorption of DG 6 on Y/CS/MFA rapidly reached equilibrium within 60 min and could be efficiently removed in a wide range of pH. Ca ²⁺ and most Na ⁺ in SA molecule carried out ion exchange and formed a stable network-structure polymer SA/Ca gel pellets, which can effectively remove acid dyes from wastewater, and are easy to be separated after adsorption. The intra-day and inter-day RSDs were 1.44–6.11% (n = 6) and 3.12–11.70% (n = 6), respectively. Se realizaron ensayos desnitrificantes en lote con 10 mg CCH3COO- L-1 y con 10 mg C-E2 L-1. The highest removal capacities were registered using MWCNT (224.6 mg/g for CZ and 78.8 mg/g for DA), which are highly efficient performances, when compared with other adsorbents reported in the literature. The results of mean sorption energy from Dubinin–Radushkevich (D–R) model and FTIR analysis revealed that the adsorption should be the double properties of physisorption and chemisorption. The mechanism of adsorption has also been discussed. It also found that H-bonding, π–π interaction, and electrostatic interaction were the main mechanisms in the process of BPS adsorption onto the CCAC. The GAC and AE columns showed a poor correlation between DOC and PFAS removal efficiency. The remarkable adsorption of AR1 and JGB over KOH-900 could be explained by the combined mechanisms of hydrophobic, π–π, electrostatic and van der Waals interactions. Carbon-based adsorbents possess exceptional adsorption capability, making them an ideal platform for the remediation of environmental contaminants. The Swedish National Food Agency has determined that the drinking water of over one third of the country's municipal consumers is at risk or already affected by PFAS contamination. Many researchers have tried various conventional treatment techniques such as advanced oxidation process, physical adsorption, and biological treatment for the elimination of antibiotics. The ANOVA test results showed that Fe 3þ ion significantly affected and decreased TC adsorption onto the MWCNT (p value < 0.05), while other studied cations and anions did not affect TC adsorption (p value >0.05). For this reason, MIL-101 with two functional groups capable of H-bonding (MIL-101-(OH)2) exhibited remarkable adsorption capacity based on adsorbent surface area. The equilibrium data were better explained by the Langmuir isotherm model and subsequently the adsorption capacity (qm) based on the Langmuir model was 6.784 mg g⁻¹. In this study, we report a novel biomass‐derived porous carbon nanostructures (BD‐PCNSs) obtained from Lantana camara stem (LAC) using a simple and low‐cost preparation method. The results also offered an attractive alternative for the extraction and determination of paraben preservatives in a complex matrix, such as cosmetics. Kinetic of atenolol adsorption in granular activated carbon was evaluated using pseudo-first and pseudo-second order models. Therefore, more effective techniques for wastewater treatment especially antibiotic removal are necessary. The intra-particle diffusion and film diffusion were believed to be the rate-limiting process for both two adsorbents. The prepared products were characterized by X-ray Diffraction pattern (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Ultraviolet–Visible absorption (UV–Vis), Energy Dispersive X-ray (EDX), and Fourier Transform Infrared spectroscopy (FT-IR). Controlling water pollution has become challenging in recent years. Adsorption process could be described by pseudo-second-order kinetic model. The Liu isotherm model best fitted the experimental data. Throwing away in "household garbage" was an important disposal mechanism for unconsumed caffeinated products. 4. Polydopamine nanospheres (PDA) was designed to serve as a new substrate for surface-enhanced desorption/ionization mass spectrometry (SELDI-MS). Vibrating Sample Magnetometer (VSM) was used to study the magnetic properties of the products. The obtained nano-composites were proven to be of sufficient quality for an ideal RAM-SPE adsorbent with a large specific surface area of 369 m² g⁻¹, uniform mesopores of 2.8 nm, and special phenyl-functionalized pore-walls. Overall, this study is believed to enlarge the application of MOFs on the removal of emerging contaminants from waters. Studies have found the presence of ECs in surface water, groundwater, stormwater, treated wastewater, treated industrial effluent, bottled water and snow from glaciers in Indo-Chinese border which contaminate water bodies. BPA has been widely used in the manufacture of sunscreen lotions, nail polish, body wash/lotions, bar soaps, shampoo, conditioners, shaving creams, and face lotions/cleanser, besides its other industrial applications. Caffeine, clofibric acid, diclofenac, gallic acid, ibuprofen and salicylic acid were selected as representative contaminants. The presence of other ions in solution besides arsenic can affect arsenic adsorption; therefore, several ions commonly found in water were tested to determine their effect on arsenic adsorption ⦠The triclosan equilibrium concentration was measured spectrophotometrically, the morphology of the activated carbon characterized by scanning electron microscopy, and the amount of the adsorbed triclosan on the activated carbon quantified by a mass balance method. In this book chapter we analyze the application of biochar for dyes with particular focus on CR. The photocatalytic performance is connected to the large surface area of graphene derivatives (e.g. Moreover, PS-GO outperformed a commercial granular activated carbon (GAC) at low contact times and compared well at longer contact time for OFLOX, Rh, BP-3 and TRX suggesting the suitability of the newly introduced material for drinking water treatment. Among these contaminants, stand out dyes, heavy metals, pharmaceuticals, fluoride, arsenic species, rare earth elements, pesticides and personal care products. The adsorption data were analyzed to discuss the influence of carbon properties and adsorbate properties on adsorption effectiveness and rate. Its thermodynamic studies indicated endothermic and spontaneous process. 6. The structure, morphology, and textural properties from both AC were analyzed by scanning electron microscope (SEM), pH of point-zero-charge (pHPZC), infrared spectroscopy (FTIR), and N2 adsorption/desorption isotherms. Many affordable techniques such as activated sludge and adsorption by agricultural adsorbents showed high efficacy in treating high levels of different pesticides. Besides that, the organic chemicals such as dyes, phenols, amines can cause allergy, gastrointestinal disorders, difficulty for walking, cardiovascular diseases, skin irritation, human cancer, besides of these chemicals being mutagenic. The KPC was better at reducing ivermecitn in low-concentration solution (≈75 μg/L) to less than 5.0 μg/L compared with KPA with ≈20.0 μg/L. This study reports bibliometric mapping, relevant data on studies using membranes as water treatment processes, and their viability in industrial applications. The adsorption mechanism was explained in terms of H-bonding and a partial contribution by electrostatic and π-π interactions through analyses of the adsorptive performances and surface charges of the OACs over a wide range of pH conditions. Meanwhile, the reduction of macroscopic parameters (Total Organic Concentration, TOC, Total Nitrogen, TN, carbonates (CO3²⁻) and aromaticity) in the real hospital wastewater was achieved in high percentages (from 64 to 98.8%). 2020 Oct 25;10(11):305. doi: 10.3390/membranes10110305. Thermodynamic study indicated that the adsorption was a spontaneous (?G(0)?0) and exothermic (?H(0)?0) process. Por lo que el objetivo de este trabajo consistió en evaluar la mineralización de 17B-estradiol mediante un lodo desnitrificante. Epub 2018 Sep 10. We develop, design and manufacture equipment for the removal of trace contaminants from ⦠Antibiotics, an important type of pharmaceutical pollutant, have attracted many researchers to the study of their removal from aqueous solutions. Notably, biochars provide a win-win strategy by simultaneously utilizing the waste biomass during its production and a great adsorbent for pollutant removal. But to get the job done successfully, youâll need to first ⦠Please enable it to take advantage of the complete set of features! NLM source by sustainable means for desalination There has been development of new bio electrochemical systems (BES) named as microbial desalination cell (MDC) that use bacteria to create renewable energy in the form of electricity, hydrogen, and methane. Contaminant removal efficiencies are dependant on the nature of the contaminant, the carbon type, initial levels of contamination and gas flow rates. The superior photocatalytic performance was exhibited by the TiO2/GO/CuFeO4 catalyst owing to its high adsorption performance and separation efficiency of photo generated carriers. Yet, some treatment processes, namely precipitation and ion exchange, have cost-prohibitive and potentially hazardous drawbacks. The effect of different salts including NaCl, Na2CO3, Na2SO3 and KNO3 on the adsorption of paraquat was studied. The average crystallite size of MgO and ZnO nanoparticles was calculated from their XRD data using the Scherrer equation. Under these conditions it was possible to obtain an efficiency removal of approximately 88%. The considerable interest is noticed in the research fraternity on green energy production utilizing renewable, The main aim of the project would be to design and development of new core-in-shell nano-material for water disinfection The results of this study indicate that the chemically prepared AC has excellent adsorptive capacity and can be used as an effective adsorbent for the removal of ATZ from aqueous solutions. The current review intends to investigate adsorption process as an efficient method for the treatment of ECs. Then, the adsorption behavior of the adsorbents was tested for the removal of atrazine (ATZ) herbicide as a model of organic micro-pollutant. Experimental isotherms were fitted by Langmuir, Freundlich and Sips adsorption models. Subsequently, the main applications of bionanocomposites as adsorbent materials for the removal of emerging organic and inorganic pollutants from water samples are described. After evaluating the performance of adsorbent, these materials will be employed for removing organic compounds from wastewater of textile industries, food, paper, petrochemical, pharmaceutical, polymers, etc. Research has shown that the application of different adsorbents such as, activated carbons(ACs), modified biochars (BCs), nanoadsorbents (carbon nanotubes and graphene), composite adsorbents, and other are being used for EC's removal from water and wastewater. Because of the presence of silver on the C@CoFe2O4@Ag, it also showed photocatalyst property in the photo-degradation of organic pollutants. mg/g) makes it a viable solution for wastewater treatment. However, the efficient and accessible applications of these technologies are challenging. The sorptive removal of CR on AFB was investigated under the following operational conditions (pH, 2–12; biochar dosage, 4–14 g/L; temperature, 30–60 °C; and contact time, 30–480 min). Therefore, the AC obtained from OB (containing a mixture of seed, pulp, and olive peel) has a high potential for application in removing emerging contaminants from the wastewater. Sonochemistry, an almost a century old technique was predominantly employed in the cleaning and extraction processes but this tool has now slowly gained tremendous attention in the synthesis of nanoparticles (NPs) where particles of sub-micron have been produced with great stability. Efforts were focused to establish relationships among the activation procedure, the textural and physical-chemical properties of the resulting materials and their volumetric CH4 uptake. The utilization of coagulants can be improved by showing their efficiency in comparison to the advanced treatment technologies available in the present scenario. In a more recent approach, sonophotocatalysis was employed for the combined effect of sonication and photocatalysis of metal deposited graphene. The physicochemical properties for the obtained BD‐PCNSs material were confirmed using X‐ray diffraction, scanning electron microscopy, nitrogen sorption isotherms, and X‐ray photoelectron spectroscopy. The versatile applications of the MOFs with -COOH in adsorptions from both polar and nonpolar phases are remarkable considering that hydrophobic and hydrophilic adsorbents are generally required for water and fuel purification, respectively. Nine natural clay samples, collected in the eastern Andalusian region (South of Spain), were evaluated for the retention of two widely used non-ionic fungicides, metalaxyl and fludioxonil. Finally, the presence of free -COOH in the MOFs was confirmed by liquid-phase adsorptions together with general Fourier transform infrared analyses and decreased chemical and thermal stability.
