Abstract

For the purpose of attenuating the environmental and public health hazards posed by azo dye wastewater, the degradation pathway and effect of Metallic glasses on printing and dyeing wastewater are explored. In this paper, Cu46Zr45Al7Y2 Metallic glasses is used to activate sodium persulfate to achieve the purpose of degradation of acid orange dye. At the same time, the effects of different environmental factors on the degradation effect are explored, and the cycle stability and degradation principle of Cu-based Metallic glasses are preliminarily explored. The results show that when the starting concentration of acid orange solution is 50 mg/L, the dosage of Cu46Zr45Al7Y2 band is 2 g/L, the dosage of sodium persulfate is 4 g/L, the pH is 2, the temperature is 35 ℃, and the degradation reaction lasted for 15 min, the degradation rate reaches 95.01%. In addition, after six cycles of degradation, the Cu-based Metallic glasses band still has good stability and corrosion resistance.
