<P>PROBLEM TO BE SOLVED: To provide such a constitution of an apparatus for producing reduced water that reduced water is produced in a condition that the residual amounts of a chlorine ion, a hypochlorite ion and a chlorine molecule are lowered and the elution of a base stock of an electrode in water is decreased by adjusting the time to impress positive (+) AC voltage and the time to impress negative (-) AC voltage. <P>SOLUTION: A carbon electrode 1 is selected as each of the electrodes of this apparatus for producing reduced water. The residual concentration of the chlorine ion or the like is lowered. Length of the time to impress negative (-) voltage to the carbon electrode 1 from an AC power source 3 is set so that a scale film having such a thickness that the electrical conductivity to water is not hindered is formed on the surface of the carbon electrode 1. Length of the time to impress positive (+) voltage is set to a degree that the formed scale film is dissolved and the impression of the positive (+) voltage ends before a carbon particle is eluted in water from the surface of the carbon electrode. As a result, the elution of the carbon particle in water can be decreased. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
