A novel multi-metal binding biosorbent (MMBB) was studied.
The biosorption of Cd2 +, Cu2 +, Pb2 + and Zn2 + on MMBB was evaluated.
Hydroxyl, carbonyl and amine groups are involved in metal binding of MMBB.
Equilibrium data were presented and the best fitting models were identified.
The obtained results recommend this MMBB as potentially low-cost biosorbent.
