Abstract

Removal of heavy metals by phosphate-solubilizing bacteria (PSB) activating phosphate materials in simulated heavy metal liquid environment was studied. Calcium phosphate was a kind of functional carrier material under action of PSB, accelerating the reaction to form phosphate precipitation of heavy metal. The results indicated that the removal of heavy metals with activated phosphate materials by PSB occurred within 15 days, and achieved high removal rates of Pb2+, Cu2+, Zn2+ and Cd2+ comparing with the phosphate materials inactivated. Therefore the activated phosphate materials by PSB could be a functional material for efficiently removing heavy metal from contaminated soil.
