Abstract

Methylene blue molecules in aqueous solution have been decomposed by using a novel 3D integrated
micro-solution plasma reactor operated with Ar and He gases. Energy efficiency for methylene-blue decomposition
in the case of Ar is relatively higher than that in the case of He. This result suggests that
cheaper Ar gas has brought about superior performance in water purification. In both cases of Ar and He,
methylene-blue decomposition efficiency is one order of magnitude higher than that of conventional solution
plasma.
