Abstract:
... This study examined the effect of potassium permanganate (KMnO₄)-modified activated carbon for formaldehyde removal under different face velocities and different initial formaldehyde concentrations in building environment. We chose the coconut shell activated carbon due to their high density and purity. Moreover, they have a clear environmental advantage over coal-based carbons, particularly in te ...

Abstract:
... Electrochemical oxidation was proposed as a promising technology for algal control in drinking water treatment. To be effective, the electrogenerated oxidants should have long half-lives and could continually inhibit the growth of algae. In this study, we used the electrochemical system equipped with a Ti/RuO₂ anode which focus on generating long half-life chlorines and H₂O₂. We explored the impac ...

Fourier transform infrared spectroscopy; adsorbents; adsorption; aqueous solutions; bisphenol A; dimethyl sulfoxide; emulsions; hydrogels; kinetics; methanol; microparticles; models; moieties; pH; particle size; polymerization; sorption isotherms; surface water; ultraviolet radiation
Abstract:
... Hydrogel microparticles (HMPs) were synthesized via reverse emulsion/UV light polymerization and employed as adsorbents for removing bisphenol A (BPA) from aqueous solution. Results demonstrated the smooth surface of HMPs, with particle size ranging from 137 to 535 μm. Functional groups, including –OH, C–O, C=O, and C–H, are all involved in BPA adsorption confirmed by FTIR. Effect of solution pH, ...

Subject:
adsorption; aquatic environment; desorption; electrostatic interactions; environmental factors; ion exchange; kinetics; marine sediments; models; oxytetracycline; phosphates; salinity; sorption isotherms
Abstract:
... The fate and transport of antibiotics in the aquatic environment are usually influenced by the combined effects of environmental factors. In this study, batch-type experiments were conducted to investigate the combined effects of phosphate and salinity on oxytetracycline (OTC) adsorption on, and desorption from, two marine sediments. Pseudo-second-order kinetic model fitted the kinetic data better ...

Abstract:
... This study investigated the efficiency and mechanisms of Cd²⁺ removal by chicken-manure biochar produced at different temperatures. Adsorption kinetics, isotherms, thermodynamic, and desorption were examined, and the biochars before and after adsorption were analyzed by SEM-EDS, FTIR, Boehm titration, and XRD. Kinetics of adsorption were better described by pseudo-second-order kinetic model than p ...
