Abstract

The solubility of radium, barium, and lead nitrates in aqueous solutions of acetic acid and its mixtures with 0.5 to 16 M nitric acid was determined. For aqueous solutions of acetic acid, the solubilities of radium, barium, and lead nitrates decrease monotonically with increasing mass fraction of CH₃COOH, and for glacial acetic acid they are 0.0027, 0.010, and 0.069 g/kg solvent, respectively. For mixtures of acetic and nitric acids, the solubilities pass through a minimum corresponding to 96–99 wt % CH₃COOH.

硝酸镭、钡和铅在CH3COOH-HNO3-H2O体系中的溶解度

测定了硝酸镭、硝酸钡和硝酸铅在醋酸及其与0.5 ~ 16 M硝酸混合水溶液中的溶解度。在乙酸水溶液中，镭、钡和硝酸铅的溶解度随着CH3COOH质量分数的增加而单调降低，在冰醋酸中，它们的溶解度分别为0.0027、0.010和0.069 g/kg溶剂。对于醋酸和硝酸的混合物，溶解度通过相应的96-99 wt % CH3COOH的最小值。
