摘要：

The photodegradation of Acid blue 74 in aqueous solution employing a H2O2/ultraviolet system in a photochemical reactor was investigated. The kinetics of decolorization were studied by application of a kinetic model. The results show that the reaction of decolorization followed pseudo-first order kinetics. We demonstrate that there is an optimum H2O2 concentration, at which the rate of the decolorization reaction is maximum. Irradiation at 253.7 nm of the dye solution in the presence of H2O2 results in complete discoloration after ten minutes of treatment.
