Biosorption and its more specific form, bioaccumulation, are the newly developed procedures for recovery of metals from aqueous environments which have considerable advantages in comparison with the classical separation methods. The affordable cost, biocompatibility, non-toxicity, high selectivity, large capacity and separation rate, high potential of recovery and reuse of biosorbent, the possibility to recover the adsorbed compounds as well as low sludge production rate are the main benefits of biosorption. In the current study, different perspectives of biosorbents classification are presented. The most common biosorbents are introduced and the main mechanisms involved in both biosorption and bioaccumulation processes are explained.
