Hydroxy Phosphonic Acid Group을 배위자로 하는 킬레이트 수지
Chelating Polymer Containing Hydroxy Phosphonic Acid Group
The chelating resin was prepared through tee acetylation and phosphorylation and further though the hydrolysis from the matrix polymer which was synthesized by β-pinene and furfural. The chelating polymer of the three-dimentional networks structure was obtained. In the study of the uptake to Li(Ⅰ), Ca(Ⅱ), Na(Ⅰ), Mg(Ⅱ), Cu(Ⅱ), UO2(Ⅳ), Co(Ⅱ), Zn(Ⅱ), Ni(Ⅱ), Mn(Ⅱ), Cr(Ⅱ), Fe(Ⅲ), Ti(Ⅳ), V(Ⅳ), Cu(Ⅱ) and UO2+2(Ⅵ) were extremely high while alkali and alkali earth metals are rarely complexed with the chelating resin at pH 7 of more. From these results, the chelating resin containing hydroxyphosphonic acid functional group was considered to be used a chelating polymer with selective uptake. But the uptake of Cu(Ⅱ)and UO2+2(Ⅵ) in excess of the chelating resin showed little effect by pH increase.
