We explored the preparation of Fe-Mn oxide-biochar composites and applied them for the removal of arsenic (As) from aqueous solutions. All composites exhibited high As removal efficiencies that increased with increasing pH within the investigated range (pH 3–7). According to the equation fitting for adsorption processes, F3M1BC18 (biochar:FeSO4:KMnO4, the weight ratios of 18:3:1) had the greatest...
Due to the severity of arsenic contamination of soil and water resources around the world, finding new adsorbents for arsenic removal from the water is of high importance. The present study investigates the possible use and effectiveness of starch-stabilized Fe/Cu nanoparticles for adsorption of arsenic from aqueous solutions. First, Fe/Cu nanoparticles at various starch concentrations of 0, 0.02,...
