[11p-Z05-4] Decolorization of Aqueous Solution s of Azo Dye by Atmospheric Pressure Plasma Jet

〇(M2)Daisuke Sato1, Yoshiki Oda2, Hiroshi Kuwahata1 (1.Tokai Univ., 2.Tokai Univ. Res.)

Keywords:atmospheric-pressure plasma, the Tartrazine aqueous solution the Amaranth aqueous solution, decolorization

An atmospheric-pressure plasma jet was irradiated onto aqueous solutions of Azo dye.
The Tartrazine aqueous solution (yellow) and the Amaranth aqueous solution (red) gradually became lighter with increasing plasma irradiation time, and they were decolorized after 60 min of irradiation.
