Abstract
The invention relates to processes of decontaminating by electrochemical attack, a metal workpiece or solution contaminated with one or more metal oxides. A metal workpiece or solution contaminated with one or metal oxides is mixed or exposed to a solution including hydrazide ions to complex metal ions of the metal oxides with hydrazide ions. The metal workpiece or an anode is connected to a positive terminal of means for providing direct current. A cathode is disposed away from the metal workpiece in the solution including metal ions complexed with hydrazide ions and connecting the cathode to a negative terminal of means for providing direct current. DC current is conducted from the metal workpiece through the solution including metal ions complexed with hydrazide ions to the cathode. The solution or workpiece is decontaminated by plating out the metal ion as a metal at the cathode thereby removing the metal oxides from the metal workpiece or solution.
