Abstract
The paper studied the U(IV) and U(VI) polarographic behaviour in the E DTA presence and absence, in order to work out uranium determination m ethods, in the two oxidation states, i.e. from salts and oxides, on 0. 1M NaClO4 support and at pH = 3 for U(IV) and pH = 4 for U(VI). The me thod can be applied to a determination of 0.1-1 m M U(IV)-EDTA and U(V I)-EDTA, at a relative error of +/-1%.
