Sažetak
The A. C. polarographic method is proposed for the determination
of potassium in precipitates of the system: uran yl nitratepotassium
hydroxide-potassium nitrate. Samples containing potassium
and uranium were dissol ved in 4 M nitric acid, present
u ranium was r emoved by continuous extraction with tetrahydropyrane.
After mineralization with concentrated nitric ac id and
hydrogen peroxide, the samples were dissolved in supporting e l ectrolyte:m0.075 M tetramethylammonium hydroxide and 0.075 NI tetramethylammonium chloride. From 2.8 to 28 μg of potassium per ml.
could be determined with a standard error of 0.4 ~tg K/ml. The
l owest gramatomic ratio K/U was 3.5 X 10-5 i. e. 5.6 ppm of K in U.
