Sažetak

The electrokinetic potential was measured for uranium oxide
samples of different atomic ratios O/U, ranging from 2.00 to 2.45.
It was found that the differences in the oxidation states correspond
to small but significant differences of the electrokinetic
potential, with higher values. for lower oxidation states. The
reversal of sign has been observed for positive suspensions at
pH = 3.3 by the phosphate counter ion. The electrokinetic po tential
was found to be independent of the us+ /U4+ ratio in
the solution, indicating that these ions are not potentia l
determining.
