Paper Abstract

We have tried to control water pH by a micro pH control system. We fabricate the micro chip system for pH control constructed with a photoresist channel and integrated electrodes. In this system, the micro channels are set onto the electrodes and electrical field is applied to the electrodes. As a result, the pH of de-ionized (DI) water is can be changed from 7.0 to 7.4. In a macro system using a glass beaker and Al electrodes, the water pH can be changed from 7.3 to 8.6. We believe that this study can contribute to bio-electronics, medical and agriculture fields.
