摘要

The degradation of an azo dye crystal violet by UV/Fenton oxidation process in the presence of heteropolyacid solution has been investigated. The degradation rate is strongly dependent on the pH, initial concentrations of the dye, Fe2+, H2O2 and phosphotungstic acid. The effect of these parameters has been studied and the optimal reacting conditions were experimentally determined. It was found to be initial pH 2.7, [H2O2] =71 mM, [Fe2+] = 0.5 mM, [dye]0 = 20 mg/L, phosphotungstic acid concentration is 24 mg/L. Under optimal conditions, 95% degradation efficiency of dye in the presence of heteropolyacid solution was achieved after 60 min of reaction. The experimental results showed that the UV/Fenton oxidation process was an effective process for the degradation of crystal violet at low H2O2 and Fe2+ concentrations. Meanwhile, this research also proved that heteropolyacid could improve the photocatalytic efficiency in the UV/Fenton reaction as an efficient activator.
