Abstract
The influence of elevated temperatures on the formation of 1:1 chloro compl exes for Eu3+ and Am3+ reported. Using a solvent extraction technique, stab ility constants for the equilibrium Mi((aq))(3+)+Cl-(aq)(-)<->MCl(aq)2+ hav e been measured in the temperature range of 25-75 degrees C. Modest increas es in beta(1) are observed, and small positive enthalpies for these reactio ns are reported. These data are discussed in the context of previous report s for the trivalent lanthanide and actinide chloro systems.
