碱金属的硝酸盐与硝酸铀酰和水所成体系溶度的研究,对于某些萃取过程说来,无论在理论上,还是在实际应用上,均具有一定的意义。但文献中关于这方面的研究工作,还很不足。对于LiNO_3-UO_2(NO_3)_2-H_2O体系,则只出现过与的一篇报道,他们研究的温度为0°与25℃。发现在这些温度下的固相均为LiNO_3·3H_2O与UO_2(NO_3)_2·6H_2O,文中虽曾指出固相组成是用什列涅玛格尔斯(Schreinemakers)湿渣法确 The study on the solubility of alkali metal nitrate with uranyl nitrate and water is of some significance to some extraction processes, both in theory and in practice. However, the literature on this aspect of research work, is still not enough. For the LiNO_3-UO_2 (NO_3) _2-H_2O system, there is only one report. The temperature of their study is 0 ° and 25 ° C. It is found that the solid phases at these temperatures are LiNO 3 · 3H 2 O and UO 2 (NO 3) 2 · 6H 2 O. Although the solid phase compositions have been identified using the Schreinerkers wet slag method
