摘要

从盐酸水溶液中提取金属(如镓和铁)的不同有机溶剂萃取系数的温度依赖性已被证明取决于金属浓度。对这些数据进行了分析,得出了萃取酸在有机相中的解离熵和解离焓。讨论了所得值的特殊性。

Solvent extraction from halide solutions. Part V. Temperature-dependence and dissociation of ion pairs
The temperature-dependence of the extraction coefficients of different organic solvents for metals, such as gallium and iron, from aqueous hydrochloric acid solutions, has been shown to depend on the metal concentration. The data have been analysed to yield entropies and enthalpies of dissociation of the extracting acids in the organic phase. The peculiarities of the values obtained are discussed.
