The objective of this research is to develop poly(vinylbenzyl chloride)-supported chelates that would lead to applications in the removal of radionuclides from nuclear fuel wastewater, as well as from the environment (whether as a tool for environmental remediation or hydrometallurgy).Poly(vinylbenzyl chloride) was modified with ethylenediamine, diethylenetriamine and tetraethylenepentamine, respectively, then phosphorylated with diethyl chlorophosphate for subsequent metal ion studies. Additionally, the effect of ligand rigidity on complexation was determined by comparing phosphorylated products of 3-hydroxypiperidine and methylethanolamine-modified resins.Elucidation of structures was achieved by measuring the acid, nitrogen and phosphorus capacities of each resin. Further characterization was achieved by FT-IR, while metal-ion uptake was determined by ICP-OES.
