中文摘要: 通过饱和容量法、等摩尔系列法、斜率法确定了氨基膦酸树脂吸附铥、镱、镥混合稀土离子时所形成的配合物的配位比为1.5∶1,吸附过程既有单分子螯合配位,也有双分子螯合。通过红外光谱初步分析判断,氨基膦酸螯合树脂功能基中的氮、氧原子与稀土配位成键,形成了配位化合物。

Abstract:The molar coordination ratio of complex formed by sorption of amino methylene phosphonic acid resin from mixed solution of thulium, ytterbium, lutetium was determined as 1.5∶1 through saturation volumetric method, equimolar series method and slope method. The absorption mechanisms include single molecular and double molecular chelate coordination. Based on IR spectrometry, the preliminary analysis indicates that nitrogen, oxygen atoms in functional group of APAR coordinate with Tm-Yb-Lu ion to form bonding and coordination compound.
