METHOD FOR PRODUCING WATER INCLUDING MORE EXCESSIVE HYDROGEN IONS OR HYDROXIDE IONS THAN COUNTER IONS AND WATER THUS OBTAINED

摘要

PURPOSE: To provide a technique which is suitable for washing or surface treatment and by which water contg. hydrogen ions or hydroxide ions of more excessive concentration than counter ions that is easily subjected to waste liquid treatment is effectively produced, and to provide the water contg. hydrogen ions or hydroxide ions of more excessive concentration than counter ions. ;CONSTITUTION: In a method for producing water contg. more excessive hydrogen ions or hydroxide ions than counter ions, an electrolyzer of a three-chamber construction consisting of an anode chamber 9 provided with an anode electrode 2, a cathode chamber 8 provided with a cathode electrode 1 and an intermediate chamber 5 put between the anode chamber 9 and the cathode chamber 8 is used. Water is fed to the anode chamber 9 and/or the cathode chamber 8, and also electrolytic treatment is made on condition that there is electrolyte in the intermediate chamber 5 to produce water contg. hydrogen ions or hydroxide ions of more excessive concentration than counter ions.;COPYRIGHT: (C)1995,JPO
