- •
Key constituents and feature of the biopolymer binding heavy metals were disclosed.
- •
Biopolymers with different proportions of constituents were extracted from sludge.
- •
Adsorption capacities of the biopolymers for Cu2+ varied with their constituents.
- •
Proteins were the key constituents of the biopolymer for the adsorption of Cu2+.
- •
High proteins/polysaccharides ratio was beneficial to the adsorption of Cu2+.
