Evaluation of Micro Plasma formed in the Narrow Gap in Electrolyte Solution

Micro-plasma has been investigated because of its unique nature and possible application using high energy in the field of chemical / electrochemical system. Plasma phase can be produced by applying high voltage at higher than 100 V to the electrode immersed in aqueous electrolyte solution. For example, properties of glow discharge contact electrode (GDCE) and related phenomena occurring on this electrode has been studied. The plasma sheathe cover the electrodes and emits light containing atomic emission lines of elements sputtered from the electrode surface and induced from electrolyte solution 1,2). The plasma electrodes have been therefore considered as a tool for elementary analysis method. One of drawbacks of this method is consumption of electrode due to sputtering by high temperature plasma an
