Heavy metal pollution has been a focus with increasing attention, especially Pb2+ , Cd2+ , and Ni2+ in an aqueous environment. The adsorption capacity and mechanism of extracellular polymeric substances (EPS) from Agrobacterium tumefaciens F2 for three heavy metals were investigated in this study. The adsorption efficiency of 94.67%, 94.41%, and 77.95% were achieved for Pb2+ , Cd2+ , and Ni2+ adsorption on EPS, respectively. The experimental data of adsorption could be well fitted by Langmuir, Freundlich, Dubinin-Radushkevich isotherm models, and pseudo-second-order kinetic model...
