<P>PROBLEM TO BE SOLVED: To provide a modification and improvement method by which electrodes are directly brought into contact with an object solution such as health drinking water, a raw material solution of health drinking water, drinking water, refreshing beverage, mineral water, juice, coffee, milk, tea, green tea, their mixed solutions, liquors, and electrification is carried out. <P>SOLUTION: Voltage is applied to the electrodes 1 and 2 and the object solution is fed to an electrolytic bath. An electrochemical reaction (oxidation) occurring in an anode is isolated from an electrochemical reaction (reduction) occurring in a cathode by using a diaphragm such as a cation membrane 4. The kind and presence of the diaphragm differ in use according to the kind and the treatment purpose of the object solution. When treatment is carried out so as to improve reducing power of the object solution and to prevent oxidation as one example, a method by which the object solution is fed to a minus bath (reducing bath) and water of city water level is fed to an oxidizing bath is performed. When a metal such as vanadium, is used as the anode, vanadium is eluted and a vanadium ion is increased in the object solution. A desired metal ion is dissolved in the object solution by changing the substances of the anode. <P>COPYRIGHT: (C)2004,JPO |
