摘要： In order to regenerate permanganate solutions being utilized for the etching and roughening of plastics surfaces electrolytic methods are known. Though relatively small quantaties of by-products are produced with these methods as compared to chemical regeneration methods, large quantaties of manganese dioxide are produced when printed circuit boards are treated. In order to avoid formation of manganese dioxide during the regeneration method a novel cathode 2 has been found which is provided with a porous, electrically nonconducting layer 7 on the cathode body 3. The layer 7 preferably consists of a plastics material being resistant to acid and/or alkali.

摘要： The invention relates to a process for the production of a peroxodisulfate, such as ammonium-, sodium- and potassium peroxodisulfate by anodic oxidation of an electrolyte containing a sulfate and/or hydrogen sulfate. The disadvantages of the conventional platinum anodes used for this hitherto can be avoided by using as the anode a diamond film mounted on a conductive carrier and made conductive by doping with a tri- or pentavalent element and by not adding a promoter to the anolyte.

摘要： A water treating apparatus is provided which is capable of producing a hypochlorous acid-containing electrolytic water having a satisfactory sterilizing ability in a household. The water treating apparatus is an apparatus for producing hypochlorous acid in for-treatment water containing a salt by use of an electrochemical reaction which occurs in the for-treatment water when a direct current voltage is applied to at least a pair of electrodes oppositely disposed in the for-treatment water, wherein the direct current voltage to be applied to the electrodes is obtained by smoothing an alternating voltage of domestic use power supply into direct current power of a predetermined voltage, an electrode having titanium covered with a coating containing at least palladium or-ruthenium is used as an anode, and at most 90% of the salt added to the for-treatment water is converted into hypochlorous acid by the electrochemical reaction.

摘要： An electrolytic production of sodium persulfate in a decreased number of steps with low unit power cost is described. Sodium persulfate is caused to crystallize by the reaction between an anode product and sodium hydroxide. The resulting sodium persulfate slurry is separated into a mother liquor and sodium persulfate crystals which are recovered and dried to obtain product sodium persulfate. In the process of the invention, ammonia liberated in the reaction-type crystallization of sodium persulfate is recovered into a cathode product, which is then neutralized by sodium hydroxide and/or ammonia. The neutralized solution is combined with sodium sulfate recovered from the mother liquor after recovering the sodium persulfate crystals and reused as a part of the starting material for an anolyte feed solution.
