抄録

Parallel operation of pulsed plasma generated inside bubbles is successfully demonstrated by applying fast rising voltage to a multi electrode system mounted in treat water. A 10 ppm acetic acid which is not decomposed by ozone is used as persistent materials in water and the decomposing efficiency of that material is evaluated by measuring TOC values in water. The electric conductivity of treat water affects the decomposing efficiency because the water resistor that is inversely proportional to the conductivity limits the plasma current flowing along the surface of bubbles that are generated by feeding oxygen gas. With nine parallel electrode system, the decomposing efficiency of acetic acid shows higher values than that with a single electrode system. The emission of OH radicals generated in plasma was observed by spectroscopic measurements.
