轻稀土硝酸盐及其水合物制备的研究

The Investigation of Preparation for Light Rare Earth Nitrates and Their Hydrates

在文研究了轻稀土硝酸盐及其水合物的几种制备途径,并研究了高水合物的干燥条件。提出了制取Ln(NO_(2))_(3)·nH_(2)O(Ln=La,Pr,Nd,Sm;n=6,5,4,2,1)和La(NO_(3))_(3)的实验方法。

The various methods for preparing light rare earth nitrates and their hydrates and the drying conditions of these hydrate crystals have been investigataed.The practical methods for preparing Ln(NO_(3))_(3)nH_(2)O(Ln=La,Pr,Nd,Sm;n=6,5,4,2,1)and La(NO_(3))_(3) have been presented.
