D751螯合树脂吸附铀酰、铜、镍、锌及钴的研究

THE SORPTION BEHAVIOURS OF UO_2~2+, Cu^2+ , Ni^2+ , Zn^2+ AND Co^2+ ON THE MACROPOROUS CHELATING ION EXCHANGE RESIN D751

本文研究了国产的具有亚胺二乙酸功能基的大孔螫合树脂D751对铀酰、铜,镍、锌、钴等5种二价离子的吸附性能。测定了树脂对5种二价离子的吸附量与溶液pH值的关系曲线;测定吸附有二价离子的树脂的红外光谱及螯合物解离pH值(DpH)。

The sorption behaviours of UO22+, Cu2+ , Ni2+, Zn2+ and Co2+ on the macroporous chelating ion exchange resin D?51 containing iminodiacetic acid as ligand are studied, and the iesin's sorption capacity as function of solution pH, the chelate-decomposition pH (DpH) and I.R. spectroscopy of resinates are reported in this paper.
