Sažetak
Electrochemical redox processes of uranium (VI) and uranium
(V) in aqueous solutions of acetylacetone have been studied
by means of various electrochemical techniques.
The presence of acetylacetone accelerates the rate of disproportionation
of uranium (V), even under conditions such that
uranium (VI) is not in the form of the acetylacetonato complex.
The corresponding rate constants of disproportionation were determined.
The influence of the acetylacetonato ion concentration on the
potential and on the rate of the uranium (VI) - uranium (V) electron
transfer was investigated by means of cyclic voltammetry and
squa,re-wave polarography. Both reduction and oxidation of uranium (V) were investigated by using the Kalousek commutator technique. A mechanism for those processes is proposed.
It was proved by electrocapillary measurements that besides
the adsorption of acetylacetone, adsorption of several uranium
acetylacetonato species plays an important role in the overall
mechanism. Taking into account the experimental results, the redox processes of uranium (VI) and uranium (V) in the presence of acetylacetone can be explained in terms of an ECE mechanism.
