摘要
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.
