Recently, glow discharge in aqueous solution has been used to decompose the organic pollutants, because it has generate not only hydroxyl radicals but also atomic oxygen having high potential oxidation power. In this work, we carried out to decompose Rhodamine B (RhB) from aqueous solutions in the presence of liquid phase plasma (LPP) system. Properties of generated plasma were investigated by optical emission spectroscopy methods. The results of electrical-discharge degradation of RhB showed that the decomposition rate increased with the applied voltage, pulse width, and frequency. The oxygen gas addition to reactant solution increases the degradation rate by active oxygen species. The RhB decomposition rate was shown to increase with the TiO2 particle dosage. |
