| Abstract |
The causes of disease and aging found in modern science are called free radicals, which are toxic in humans. As a method for removing such active oxygen, water has been studied in various ways. Dissolved hydrogen water is an antioxidant that removes free radicals stored in the human body. Dissolved hydrogen water has a reduced value in which the redox potential (ORP) is negative in water. This role of reduction removes or releases free radicals from the body. In general, there are two methods of easily making dissolved hydrogen water: a method of placing water in a magnesium container and a method of dissolving hydrogen by injecting hydrogen gas into the water. The downside of this approach, however, is that you have to wait for 20 to 30 minutes, or when you're exposed to the air, the hydrogen quickly disappears into the atmosphere. Therefore, in this paper, when the dissolved hydrogen water is produced by electrolysis, hydrogen is adsorbed to the minerals without the waiting time, and the dissolved time of hydrogen in the water becomes longer. And with multi-stage control, the user can easily get the required amount of dissolved hydrogen. To make this, the amount of dissolved hydrogen in each stage was measured and measured by PWM voltage control. Finally, in this study, other components contained in dissolved hydrogen water generated by electrolysis method of PWM voltage control, ozone, chlorine, trihalometal, etc. are not measured. This may be necessary. |
