Removal of Rhodamine B Dye by Plasma Jet Oxidation Process

Recently, nonthermal atmospheric pressure plasma has been developed as a novel tool in removal of water pollutants. Rhodamine B dye, widely used textiles and biology, is toxic to both humans animals, hence removing residual solution necessary. In this work, we have setup cold jet system it effectively remove the solution. We shown that main oxidation substance responsible hydroxyl radical (•OH). By studying effect hydrogen peroxide (H2O2) concentration initial later was produced solution, power, Ar gas flow speed on dye rate, identified 2 reaction pathways generate Both these involve high-energy electrons interacting with O2 ambient air. Our work provides important information understand mechanism by treatment.
