摘要： An ice composition obtained by freezing a liquid containing, dissolved therein, hydrogen peroxide produced by electrolysis; and a method of food storage using the composition. Hydrogen peroxide has a lower rate of dissipation into the air and better suitability for long-term storage than ozone. Furthermore, since hydrogen peroxide is electrolytically produced, it eliminates the trouble of transportation, storage, and dissolution. When seawater is used as a feed water for electrolysis, the ice composition thus obtained has a higher cooling effect because it has a melting point lower than 0° C.

摘要： A method is disclosed, which is capable of subjecting microorganisms to sterilizing or bacteriostatic treatment with good efficiency as compared with the conventional sterilizing or bacteriostatic method using a noble metal electrode. Microorganism-containing water to be treated is electrochemically treated using an anode having conductive diamond to bring the microorganism into contact with the anode, thereby undergoing sterilization. Since the conductive diamond has a high oxidation potential as compared with other electrode substances, direct oxidation reaction due to contact between a microorganism in water to be treated, such as Legionella bacteria, and the anode surface occurs strongly as compared with other electrodes, thereby enabling effective sterilization. The conductive diamond has a high ability to generate ozone and has an excellent formation efficiency with respect to the generation of hydrogen peroxide and radicals. Accordingly, an indirect sterilizing effect can also be expected.

摘要： An electrolytic treatment apparatus and method by simply subjecting a chemical plating waste liquor containing phosphorus components and organic compounds to electrolytic treatment, thereby reducing the amount of impurities in the waste liquor to a level at which the waste liquor can be discharged. The chemical plating waste liquor containing hypophosphorous acid, phosphorous acid and organic compounds is subjected to electrolytic treatment in an electrolytic cell having a conductive diamond electrode as an anode. The conductive diamond electrode oxidizes or oxidatively decomposes the phosphorus components and organic compounds in the waste liquor substantially simultaneously, thereby reducing the amount of impurities to a level at which the waste liquor can be discharged.

摘要： An electrolytic cell and method of electrolysis for producing hydrogen peroxide at a moderate current density while preventing metal deposition on the cathode surface. A feed water from which multivalent metal ions have been removed and in which a salt of a univalent metal, e.g., sodium sulfate, has been dissolved in a given concentration is prepared with an apparatus for removing multivalent metal ions and dissolving a salt in low concentration. The feed water is supplied to an electrolytic cell. Even when electrolysis is continued, almost no deposition of a hydroxide or carbonate occurs on the cathode because multivalent metal ions are not present in the electrolytic solution. Due to the dissolved salt, a sufficient current density is secured to prevent an excessive load from being imposed on the electrodes, etc. Thus, stable production of hydrogen peroxide is possible over a long period of time.
