Abstract

The heterogeneous equilibria LnCl3 (solution in H2O)-HP(As)UO6·4H2O (crystal) and HCl (solution in H2O)-Ln[P(As)UO6]3·nH2O (crystal), where Ln = La, Gd, Lu, were studied experimentally, and the standard Gibbs energiess of formation of the compounds Ln[P(As)UO6]3·nH2O (Ln = La, Gd, Lu) were calculated. For the compounds La(PUO6)3·14H2O and La(AsUO6)3·15H2O the isobaric heat capacities in the range 80-300 K were measured calorimetrically, the enthalpies of formation at 298.15 K were determined, and the absolute entropies, entropies of formation, and Gibbs energies of formation were calculated. The results obtained from data on heterogeneous equilibria were compared with those of direct calorimetric measurements.
