In this paper, the degradation efficiency, effect factors and kinetics of dye Levafix Navy in UV/H2O2 system have been investigated. The results show that UV/H2O2 system has a high activity on degradation of dye Levafix Navy with so little H2O2 on so concentrated dye solution, and the photo decomposition reaction of the dye is concurrent besides the photo-oxidative degradation. The dye degradation...
Dyes are natural compounds that make the world more beautiful through coloured substances. However, the release of coloured wastewaters represents a serious environmental problem and a public health concern. Colour removal, especially from textile wastewaters, has been a big challenge over the last decades, and up to now there is no single and economically attractive treatment that can effectively...
Fe alginate gel beads were prepared and used the as the heterogeneous Fenton catalysts for the oxidative degradation of a typical azo dye, reactive blue 222 in water. The influences of some important variables on degradation of reactive blue 222 are discussed. The results indicated that Fe alginate gel beads can play a great promotion role in the photocatalytic degradation of the model dye in a wide...
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...
