Heterogeneous Equilibria in the System M~m(BUO_5)_m centre dot H_2O-Aqueous HC1

摘要

A quantitative model of the system crystalline uranoborate-aqueous solution was proposed on the basis of the experimental solubilities of M~m(BUO_5)_m centre dot nH_2O(M~m are alkaline and alkaline-earth metals)in aqueous HC1 at 25deg C.The model was used to predict the state of the heterogeneous systems under study under various conditions and to calculate the standard thermodynamic functions of the uranoborates.
