摘要： PROBLEM TO BE SOLVED: To provide an apparatus for electrolytic production of high-purity hydrogen peroxide water to be used for a washing treatment, etc., of electronic devices and liquid crystals. SOLUTION: At the time of forming atomic hydrogen in an electrolytic cell in which an anode 7 and a cathode 8 consisting of a hydrogen occlusion metal and/or alloy (more preferably palladium and palladium alloy) is housed and forming hydrogen peroxide by reducing the oxygen by the device, the anode and the cathode are segmented by using an ion exchange membrane 2 functioning as a solid electrolyte. As a result, the need for dissolving the electrolytic substance into the electrolyte is eliminated and the intrusion of the anodic substance into the hydrogen peroxide water to be formed is prevented and therefore, the hydrogen peroxide water of the high-purity free from the intrusion of impurities may be provided.

摘要： PURPOSE:To treat water to be treated without generating pollution of an electrolytic cell or electrolitic liquid and unstabilized electrolitic condition and the like by spraying ozone containing gas generated in an anode chamber of the electrolytic cell from electrolytic liquid and then bringing the same into contact with the water to be treated. CONSTITUTION:Ozone containing gas generated in an anode chamber 5 of an electrolytic cell 1 is fed from downward into an air diffusion filter 8 of a dissolving column 9 through a duct 7. On the other hand, a part of water to be treated is branched by branched water 10 and fed into the dissolving column 9 from upward, and ozone containing gas is dissolved in the dissolving column 9. Ozone containing gas branced treating water is fed into a reaction tank 13 together with the water to be branched which is not branched by a pump 12, and the whole treating water is ozone treated. Electrolytic liquid and water to be treated are not in contact with directly in said process to keep away pollution of electrolytic liquid and electrolytic process or unstabilized electrolytic condition or the like.

摘要： PURPOSE:To reduce electrolytic voltage and to increase strength and current efficiency by forming a lead dioxide electrodeposited layer contg. dispersed fine particles including beta-lead dioxide powder. CONSTITUTION:This electrode catalyst is made of a lead dioxide electrodeposited layer contg. dispersed fine particles including beta-lead dioxide powder. The electrode catalyst is produced by subjecting a base material for electrodepoosition to electrolytic treatment in an aq. lead nitrate soln. contg. suspended fine particles including beta-lead dioxide powder to form a lead dioxide electrodeposited layer contg. dispersed fine particles including beta-lead dioxide powder on the base material and by separating the lead dioxide electrodeposited layer from the base material. The electrode catalyst has higher strength than a lead dioxide catalyst layer formed by conventional hot pressing or other method and electrolytic voltage can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a water treatment method in which it is difficult to deposit metal and liquid to be treated can be treated with higher efficiency than that in the conventional method and to provide a device therefor. SOLUTION: Oxygen-containing gas is fed to a cathode 6 to produce hydrogen peroxide, and also inorganic acid is fed from an acid solution addition port 4 to an anode 5 to produce an oxidation product such as hypochlorous acid, etc., and then the liquid to be treated is treated with both compounds. Thus, the sterilizing power is enhanced and also the vicinity of a cathode 6 surface is kept in acidity from neutrality with acidity of the coexisting oxidation product and a deposition of metal hydrate is restrained.

摘要： PROBLEM TO BE SOLVED: To efficiently decompose a substance to be processed into a low molecular weight compound in an electrochemical manner by using a diamond as an anode substance and a cathode substance. SOLUTION: An anode 2 and a cathode 3, on a surface of which is covered by powder diamond, are installed separate from each other inside a box-like electrolytic cell 1. A tip part of a reference electrode 4 such as an electrode formed of mercury (II) sulfate is located between both electrodes to detect the electric potential. An aqueous solution 8 containing a substance to be processed in a raw liquid tank 7 is supplied to an electrolytic cell 1 by a pump 9 through a water feed pipe 5. The substance to be processed in the solution is brought into contact with the anode 2 and the cathode 3, and decomposed directly and/or indirectly through an oxidizing substance or a reducing substance which is to be generated through electrolysis of water, and circulated into the raw liquid tank 7 from an upper part of the electrolytic cell 1 through a circulation pipe 6. In the case of a solution or a gas small in electrical conductivity, the anode 2 and the cathode 3 are closely attached to both sides of a fluorine resin ion exchange membrane functioning as the electrolyte to proceed the electrolysis. A diamond layer is vapor-deposited on a base body to the thickness of 1-10 μm.
