摘要
Biosorption of silver ions onto A. chroococcum XU1 biomass and exopolysaccharide (EPS) was investigated. It was found that the overall biosorption process was the best when cell biomass and EPS were used together. Metal adsorption experiments showed that the final precipitate obtained by cell biomass and EPS, contained 7.85% of Ag. Based on the results presented in this study, the biomass and EPS of A. chroococcum XU1 indicated the possibility of application of them as biosorbent for removal of silver from waste waters.
