A laboratory study has been conducted to evaluate a metal decontamination process which uses a nitric acid solution of a redox agent to etch or dissolve the surface layer of the contaminated metal and thereby remove the contamination. The oxidizing species is regenerated electrolytically. it is concluded that a metal decontamination process based upon removal of contamination by treatment with a cerium(IV)-nitric acid solution (or other redox agent in nitric acid) is feasible and highly promising. 6 figures, 2 tables.
