Impacts of different salts on the degradation of acid blue 25 dye using non-thermal plasma

The color removal performance using non-thermal plasma system (NTP) corona discharge type generated from high voltage pin-to-ground plate display 82% color clearing at 11min. The total complete color removal was accomplished within 28min. Likewise, various salts as KCl, NaCl, CaCl2 and AlCl3 was used for check the influence of the conductivity. The increasing of conductivity signs that the reduction in color removal efficiency. The discharge energy and degradation competence are computed at diverse concentration for NaCl, KCl, CaCl2 and AlCl3. It was noticed that the salts compact the amount and the level of decolorization. In addition the investigated of the essential reactive species complicated in oxidation of dye organic compounds are O3 in treated water and H2O2. So the measurement for the energetic species that produced throughout the non-thermal plasma at the optimum operation time like hydrogen peroxide (H2O2), and ozone (O3). The benefits from this work in designing the plasma systems appropriate for industrial wastewaters treatment.
