摘要： Cross-linked polymeric resins from anilines linked together with polyamine alkyl chains. A process for producing the cross-linked polymeric resins by Mannich-type polycondensation of anilines and diaminoalkanes linked together by an aldehyde and subsequent basification. In addition, a method for removing heavy metals, such as Pb (II) and As (V) from aqueous solution via contacting and treatment with the cross-linked polymeric resins.
