Sažetak

The influence of surface active ag ents on the square wave
polarographic behaviour of uranyl acetylacetone was investiga t ed.
Tritone-X-100 decreases specifically the S.W. peak height of each
uranyl-acetylacetonato species, i.e. the adsorption layer is specifically
penetrable by each one. From this sp ecific depression the
over-all stability constant of uranyl acetylacetonato complexes,
in 1 M sodium perchlorate, was calculated as log ~2 = 12 .5. This
is in agreement with earlier obtained results3• Elec trocapillary
curves for T-X-100 and acetylacetone are also prese nted.
