Development of Small-sized Generator of Ozone-dissolved Water Using Boron Doped Diamond Electrodes

A new electrochemical generator of ozone-dissolved water, which is comprised of an electro-conductive diamond electrode and of an ion exchange membrane, was evaluated using tap water as source solution, in order to confirm general versatility. Although the current efficiency became lower than that obtained in the case of pure water due to the effects of co-existing substances, ozone-dissolved water of over 1 mg dm-3 can be produced. The stability was found to being over than 300 hours.
