报道了三元体系硝酸镧 -甘脲 -水 (La(NO3) 3-Glycoluril-H2 O)在 30℃时等温溶度与饱和溶液的折光率 ,绘制了相应的溶度图及饱和溶液折光率指数曲线。体系中形成新相 La(NO3) 3· 2 Glycoluril· 2 H2 O,为异成份溶解化合物。通过元素分析、红外光谱分析以及 X-射线粉末衍射分析对新相进行了表征。
The refractive index of ternary system La (NO3) 3-Glycoluril-H2 O at 30 ℃ and saturated solution was reported, and the corresponding solubility diagrams and saturation solution refractive index Index curve. The formation of a new phase in the system La (NO3) 3 · 2 Glycoluril · 2 H2 O, as the heterogeneous dissolved compounds. The new phase was characterized by elemental analysis, infrared spectroscopy and X-ray powder diffraction analysis.
