A new evaluation system of water purification by using photocatalyst has been developed and tested. The developed system, which uses a light-to-frequency converter photo IC, can solve the problems of dynamic range and precision, which are presented in a conventional evaluation system using an absorption spectrophotometer. In addition, the method of applied voltage to photocatalyst with light irradiation for water purification has been proposed.
