Solvent extraction from halide solutions. Part V. Temperature-dependence and dissociation of ion pairs

Abstract

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.
