- ... The current work exclusively pertains to preparing arsenic removing biosorbents using chicken feathers (CF) as a raw material. CF consist of keratinous proteins with many functional groups, and this paper contributes to the debate on how functional groups, especially –COOH, –NH₂ and –S–S–, interact with arsenic species before and after their modification through sorption phenomena. Chemically modi ...
