Sažetak
The precipitation of uranium(IV) from sodium carbonate
solutions has been studied. Uranium(IV) has been prepared by
electrochemic al reduction at controlled constant potential at the
-mercury cathode. From the stable solution uranium(IV) precipitates
as hydrous oxide. The dependence of the degree of precipitation
of uranium(IV) on the composition of the solution is
given, considering the carbonate to uranium concentration ratio,
th e total sodium carbonate concentration, and the pH of the
solution. Th e precipitation was induced and performed also by
raisi ng the temperature up to 60° C. Ex perimental limits of the
solubility of uranium(IV) carbonate complex es, at 60° C and at
pH = 9.5 and 10.3, indicate the possibil ity of the existence of the
uranium(IV) in solution predominantly as the [U(OH)2 (C03) 4]-6
complex .
