Water-insoluble carboxyl-containing starch graft polymers were prepared.Residual metal ion concentrations in solutions treated with the insoluble starch graft polymers were measured in different pH.The mechanism of removing heavy-metals from aqueous solutions with the carboxylated starchs was described.
