Abstract
The present paper is concerned with the isotope exchange between W-185 and tungsten, and P-32 and phosphorus respectively, in uranium(IV) trivacant Ke ggin and Dawson polyoxotungstophosphate complexes, in water. These studies were carried out at different concentrations and temperature. The isotope e xchange rate increases with the temperature and the reagents' concentration . The experimental results show that the complexes are labile kinetically.
