摘要
测定了Ｇｄ（ＮＯ_３）_３／Ｅｒ（ＮＯ_３）_３－Ｇｌｙ－Ｈ_２Ｏ三元体系在２５℃时的溶度和饱和溶液折光率。各体系的溶度和饱和溶液折光率曲线均由４支组成，分别与ＲＥ（ＮＯ_３）_３·ｎＨ_２Ｏ（ＲＥ＝Ｇｄ，ｎ＝６；ＲＥ＝Ｅｒ，ｎ＝５）、配合物ＲＥ（Ｇｌｙ）_２（ＮＯ_３）_３·２Ｈ_２Ｏ，ＲＥ（Ｇｌｙ）_４（ＮＯ_３）_３·Ｈ_２Ｏ及Ｇｌｙ相对应。
The solubilities and refractive indexes of saturated solutions of the ternary systems,Gd (NO3)3/Er(NO3)3-Gly-H2O at 25℃ have been studied and corresponding equilibrium solubility diagrams and refractive index diagrams were constructed.All the solubility curves and refractive index curves of two systems consist of four branches,corresponding to RE(NO3)3.nH2O(RE=Gd,n=6;RE=Er,n=5), ternary complexes RE(Gly)2(NO3 )3·2H2O,RE(Gly)4(NO3)3·H2O(RE=Gd, Er)and Gly.
