The aim of this paper is decolorization of a Methyl orange solution using an atmospheric pressure Argon plasma jet. When the plasma jet was directly irradiated onto a Methyl orange solution, the solution was decolorized. PH and absorbance of samples were measured before and after irradiation with various durations. Thus, non-thermal plasma jet irradiation is considered to be capable of decomposing, and can also be used for water purification.
