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.
