Abstract
Cross-linked polymer resins and related salts, solvates, tautomers or stereoisomers are described herein. The cross-linked polymer resins may comprise monomer units of N,N-diallyl aminoalkylphosphonate, a hydrophobic pendant, a tetraallylpiperazinium cross-linker, and sulfur dioxide. A method for producing the cross-linked polymer resins is described. The cross-linked polymer resins may be used as adsorbent materials for the removal of heavy metal ions and contaminant dyes from aqueous solutions. Used cross-linked polymer resins may be removed from solution, cleaned, and reused while maintaining adsorption capacity.
