ABSTRACT:
A decontaminating liquid capable of removing a radioactive substance adhering to or deposited in a metal waste is produced by a method which comprises immersing an anode made of a metal or a metal oxide having a high oxygen overvoltage equal to or higher than the oxygen overvoltage of platinum and a cathode made of a metal or a metal oxide having a low hydrogen overvoltage equal to or lower than the hydrogen overvoltage of platinum in an acidic solution having dissolved therein a metal ion in a low-oxidation state and causing passage of an electric current between the two electrodes thereby giving rise to a metal ion in a high-oxidation state.
