摘要： PROBLEM TO BE SOLVED: To solve the problems wherein, when measuring the concentration of hydrogen peroxide using an electrode sensor, accurate measurement of the concentration of hydrogen peroxide is possible if only reduction of hydrogen peroxide is generated on the electrode, while actually accurate measurement of the concentration is impossible because catalytic decomposition of hydrogen peroxide or generation of hydrogen peroxide by reduction of oxygen proceeds simultaneously. SOLUTION: This hydrogen peroxide reduction electrode 2 is formed by adsorbing at least one kind of adsorption species selected from halide ion, sulfur ion and thiol compounds onto a conductive substrate surface in the fixed state. The electrode surface is coated by the adsorption species, and thereby catalytic decomposition of hydrogen peroxide or generation of hydrogen peroxide by reduction of oxygen is prevented, and only reduction of hydrogen peroxide is generated on the electrode. Consequently, accurate concentration measurement becomes possible. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a gas diffusion cathode for reducing oxygen which is used in brine electrolysis and makes hydrogen peroxide generated on the cathode hardly deteriorate electrode performance, and to provide a brine electrolysis method with the use of the gas diffusion cathode for reducing oxygen.
SOLUTION: The brine electrolysis method comprises the steps of: accommodating the gas diffusion cathode 16 containing an electrode catalyst layer containing a silver-containing metal and manganese oxide in a cathode gas chamber 14; and electrolyzing a common salt in an electrolytic tank 11. The manganese oxide decomposes and detoxifies hydrogen peroxide generated in the cathode gas chamber 14. Thereby, the method inhibits electrode performance from degrading due to the falling of the catalyst and the lowering of electroconductivity and hydrophobicity, which are caused by the erosion of the electrode material.

SOLUTION: This electrode 2 for arsenic detection includes gold adsorbing halide ions coated on the whole conductive substrate. The electrode surface is coated by halide ions, and thereby generation of hydrogen peroxide by reduction of oxygen is prevented, and only oxidation dissolution of arsenic is generated on the electrode. Consequently, accurate concentration measurement becomes possible. COPYRIGHT: (C)2007,JPO&INPIT
