Sažetak
Complex uranyl acetylacetonato species in aqueous solution
are reduced with different sensitivity if square wave polarographic
techniques are used. From the plot of uranyl S . W. peak height
vs. the free ligand concentration, the consecutive stability constants
were obtained as: log Ki = 7.5, log K2 = 4.8, and log (32 = 12.3.
A study was made of the specific influence of acetylacetone
concentration on the S. W . peak height of different uranyl species
present in the solution. Acetylacetone molecules seem to form
an adsorption layer on the surface of the mercury drop, which is
specifically penetrable. On the basis of this assumption the over-a1i
stability constant of uranyl acetylacetonato complexes was determined
as log f32 = 12.5. All measurements were made in· 1.0 M N aC10 4
as supporting electrolyte.
