摘要： PURPOSE: To oxidatively dissolving oxide and to regenerate a liquid, by a method wherein a liquid contacted with the oxide on the surface of a metal is subjected to electrolytic oxidation on an anode and the redox potential of the liquid is moved to a noble direction from a Fermi level.
CONSTITUTION: An object to be washed having oxide on the surface of the matrix metal thereof, for example, a stainless steel pipe is immersed in the liquid containing, for example, an oxidizing agent in an electrolytic tank. The oxidizing agent is one having redox level at a more noble position, for example, a solution containing Mn
2+ , Cr
3+ , Ag
+ , Cl
- , I
- and Br
- , when electrolytic oxidation is carried out in this state, the redox level of the liquid is moved to a direction more noble than the Fermi level of the oxide and the potential in the oxide is moved to the solution side to dissolve the oxide.

摘要： PURPOSE:To decrease easily and efficiently the waste material to be decontaminated at a low temp. by bringing an electrolyte film into contact with the metallic surface to be decontaminated, bringing an electrode into contact with the surface of the electrolyte film and passing electric current between the metallic surface and the electrode. CONSTITUTION:An electrolyte film 2 is brought into contact with the place to be decontaminated of a metallic material 1 to be decontaminated. The film 2 consists of a high polymer material or gel mixed with a complexing agent or electrolyte, or a high polymer material which itself is an electrolyte. A metallic electrode 3 is brought into contact with the surface of such film 2 and electricity is conducted via an ammeter 5 to said electrode so as to make the material 1 positive pole and the electrode 3 negative pole. The base metallic material is then dissolved and the eluted metallic ion is captured by the complexing agent in the film 2. If the direction of the current is reversed, the oxide on the surface of the metallic material is dissolved and the eluted metallic ion is captured and fixed by the complexing agent.

摘要： PURPOSE: To prevent the decrease in electrolytic efficiency by providing an intermediate liquid chamber between an anode chamber and a cathode chamber, and removing the oxidative material generated in the anode chamber during electrolysis in the intermediate liquid chamber.
CONSTITUTION: An intermediate liquid chamber 5 is provided between an anode chamber 2 and a cathode chamber 8 in an electrolytic cell used in the stage of dissolving away the oxide sticking to the surface of a metallic material by using the soln. reduced by electrolysis. A titanium plate plated with platinum is put in the chamber 2 and a porous glassy carbon electrode is put in the chamber 8. 0.1M oxalic acid is put in the chamber 2 and 0.002M ethylenediaminetetraacetic acid in the chamber 8 to control to 6.5pH. 0.1M citric acid is put in the chamber 5. The oxidative or reducing material diffused from the counter electrode chambers into the chamber 5 is removed by deaerating the chamber 5, and the fluctuation of the pH is suppressed by adding a buffer beforehand.
