Sažetak

The precipitation and dissolution of uranium(VI) from aqueous
solutions containing 10-3 M uranyl nitrate and various concentrations
of orthophosphoric and nitric acid is / surveyed. The concentration
regions where (U02)s(P04h and U02HP04 are precipitated
and/or dissolved are presented by means of typical precipitation
bodies. The influence of the initial concentration ratio of nitric/
orthophosphoric acid in the precipitation system on the morphology
of (U02la(P04)2 particles formed is shown by electron micrograps.
