| Research Abstract |
Advanced oxidation process (AOP) with hydroxyl radicals (OH) is considered to be useful for sterilization through oxidation; therefore, we proposed an underwater plasma source with a porous glass membrane which functioned in bubble supply and the formation of micro-discharges.
We observed bubble formation and light emission from discharge on the surface of the membrane, respectively. The obtained results showed that AOP might be more effective because OH radicals were generated in bubbles on the porous glass membrane. Next, we observed whether B.subtilis spores could be sterilized by the underwater plasma of which operating gas was Argon. The obtained results showed that OH radical and UV emission from the plasma are responsible for the sterilization.
