Description

Solubility of crystal uranoborate of alkali and alkaline-earth metals of the composition Mm(BUO5)m · nH2O (Mm = Li-Cs, Mg-Ba) in HCl aqueous solutions 10-4-10-1 M at 25 deg C was studied. Relying on the experimental data obtained, a quantitative model of the aqueous system was suggested and physicochemical description of the uranoborates state in solutions was given. Using the method of equilibrium thermodynamics, the standard thermodynamic functions of the compounds studied were ascertained

Abstract (Russian)

Изучена растворимость кристаллических ураноборатов щелочных и щелочноземельных металлов состава Mm(BUO5)m · nH2O (Mm Li-Cs, Mg-Ba) в водных растворах 10-4-10-1 M HCl при 25 град С. На основании полученных экспериментальных данных предложена количественная модель этой водной системы и дано физико-химическое описание состояния ураноборатов в растворах. С использованием метода равновесной термодинамики определены стандартные термодинамические функции изученных соединений
