摘要： PURPOSE:To easily obtain high concn. ozone water of high purity over a long period of time by using a mixing tank wherein a filter composed of a sintered body of a titanium short fiber is arranged. CONSTITUTION:Ozone-containing gas according to an electrolytic method obtained in a gas-liquid mixed state is supplied to a mixing tank 9 wherein a filter 8 composed of a titanium short fiber sintered body having a fine mesh is arranged to be passed through the filter 8. Since this filter 8 is formed as a three-dimensional reticulated body and spaces are irregularly formed in the reticulated body, the ozone-containing gas in the gas-liquid mixed state flows out of the filter 8 in an irregular state to enter the mixing tank 9 and, therefore, the dispersion state in the mixing tank 9 becomes very well and high concn. ozone water enhanced in solubility is easily obtained.

摘要： PURPOSE:To continuously, efficiently, and economically electrolyze water without discharging a catholyte by electrolyzing water in the electrolytic cell having a diaphragm to generate oxygen or ozone and hydrogen, and returning the water to an anode chamber from a cathode chamber. CONSTITUTION:The electrolytic cell 4 is separated by an ion-exchange membrane 1 into the anode chamber 2 and the cathode chamber 3. Water or perferably pure water is supplied to the anode chamber 2 through a thin tube 7, and electrolyzed. As a result, oxygen and/or ozone are generated in the anode chamber 2, and hydrogen is generated in the cathode chamber 3. In the elecrtolysis method, the water passing through the membrane 1 from the anode chamber 2 to the cathode chamber 3 is returned to the anode chamber 2 thorough the holes 5 and 5' bored at the bottom of the cell 4 and a conduit 6 connected to the holes, and electrolysis is continued. As a result, the catholyte need not be discharged, the supply of pure water is reduced, and water can be efficiently electrolyzed.

摘要： PROBLEM TO BE SOLVED: To provide an oxygen reducing gas diffusion cathodes capable of being used under a severe operation condition through a long period in a sodium chloride electrolysis in which the electrode performance is apt to degraded because a catalyst particle supported by a base material of a gas diffusion cathode is dipped in an elecrtrolyte and a sodium chloride electrolytic method using the oxygen reducing cathode. SOLUTION: The oxygen reducing gas diffusion cathode comprises a porous conductive base material, a diamond particle having a hydrophobic surface and the catalyst particle which are formed on the porous conductive base material. The gas supply is smoothly carried out because a network is formed on the surface of the base material by the hydrophobicity of the diamond particle and the degradation of the electrode due to the active oxygen species is suppressed because the whole electrode is made hydrophobic and then, the long term stable operation is carried out.

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
摘要翻译：要解决的问题为了解决当使用电极传感器测量过氧化氢浓度时，如果在电极上仅产生过氧化氢的还原，则可以准确测量过氧化氢的浓度，而实际上精确测量浓度是不可能的，因为过氧化氢的催化分解或通过还原氧产生过氧化氢同时进行。解决方案：该过氧化氢还原电极2通过在固定状态下吸附选自卤离子，硫离子和硫醇化合物的至少一种吸附物质形成在导电基材表面上。电极表面被吸附物质包覆，从而防止过氧化氢的催化分解或通过还原氧而产生过氧化氢，并且在电极上仅产生过氧化氢的还原。因此，精确的浓度测量成为可能。版权所有（C）2007，JPO＆INPIT
