Uranium solution is obtained electrolytically by reducing uranyl ion on mercury cathode. The effect of the addition of various aminopolycarboxylic acids (such as EDTA, DTPA, CyDTA and TTHA) and organic water-miscible solvents (such as CH3OH, C2H5OH and CH3COCH3) on the stability of ura-nium in air has been investigated. The absorption spectra of uraniumand uraniumin 1 mol/l and 9mol/l hydrochloric acid solutions are examined.
