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.

However, the quality of the copper film deposited by this method is poor. In order to resolve this problem, we study the influence of some additives on two different kinds of electroless copper plating which using sodium hypophosphite as reducing agent and sodium citrate as chelating agent, sodium citrate and ethylene diamine tetraacetic acid disodium salt (EDTA·2Na). Electrochemical methods were used to test the anodic and cathodal polarization processes which can explain the mechanism of the influence of additives.
