Decontamination of metals using chemical etching

Patent ·
OSTI ID:6765446
The invention relates to chemical etching process for reclaiming contaminated equipment wherein a reduction-oxidation system is included in a solution of nitric acid to contact the metal to be decontaminated and effect reduction of the reduction-oxidation system, and includes disposing a pair of electrodes in the reduced solution to permit passage of an electrical current between said electrodes and effect oxidation of the reductionoxidation system to thereby regenerate the solution and provide decontaminated equipment that is essentially radioactive contamination-free.
