In this paper, azo dye Acid Red B (ARB) simulation of wastewater was treated with persulfuric acid. By conducting the comparative experiments of the catalysts and analyzing their catalytic mechanisms, the promotion effect of catalysts on the reaction was ranked as: AgNO3>Ag2SO4>CoCl2>CoSO4>FeSO4>FeCl2; in addition, optimum reaction conditions were attained: ARB concentration of 200mg/L, the reaction time 1h, temperature 25°C, oxidant dosage 15mL/L and 6.5×10-5mol/L with catalyst of AgNO3, under which the decolorization rate of ARB was up to 100%, and COD removal rate was up to 72%.
