The adsorption of Cu2+ and Zn2+ by extracellular polymeric substances (EPS) extracted from Klebsiella sp. J1 and competitive adsorption mechanism were investigated. Equilibrium adsorption capacities of Cu2+ (1.77mMg−1) on Klebsiella sp. J1 EPS were higher than those of Zn2+ (1.36mMg−1) in single systems. The competitive Langmuir and Langmuir–Freundlich isotherm models were proven to be effective in...
