Abstract

Crosslinked polymers made up of polymerized units of cyclic diaminoalkane, aldehyde and bisphenol-S or melamine. A method for removing heavy metals, such as Pb(II) from an aqueous solution or an industrial wastewater sample with these crosslinked polymers is introduced. A process of synthesizing the crosslinked polymers is also described.
