摘要：
Cross-linked tetrapolymers made up of different diallyl zwitterionic diallyl quaternary ammonium salt monomers, with one of them functioning as a cross-linking monomer. The cross-linked terpolymers include a repeating unit with multiple ligand centers that different metal ions can bind to. The cross-linked tetrapolymers are cationic, zwitterionic and anionic, and can be in either an acidic form or a basic form. A method of removing metal ions from an aqueous solution with these cross-linked tetrapolymers is also described.
