Abstract
Recently, it is reported that clean effect of electrolyzed alkaline water is utilized in the manufacturing processes of semiconductor and washing machine. The mechanism of this phenomenon has been explained as a hypothetical effect due to an emulsification of oils and fats by OH^- ion and a decrease in surface tension. However, the variations of thermophysical properties of water during electrolysis have never been experimentally observed. The purpose of the present study is to detect the variations of surface tension through the process of electrolysis of water. In order to measure the surface tension during electrolysis, we applied the surface laser-light scattering method. By this method, it is possible to detect the dynamic variations of the surface properties in non-contact manner.
