Title Degration of aze dyes catalyzed by metallic glasses

Abstract Due to its unique structural characteristics, metallic glasses show excellent performance in terms of thermal stability, corrosion resistance and azo dye degradation。 This paper mainly researches on the degradation of aze dyes, such as methylene blue, methylene orange and direct blue dyes catalyzed by Fe76Si9B10P5 metallic glasses。 The mother alloy was prepared by induction melting。 The Fe76Si9B10P5 metallic glasses powderes were fabricated by gas atomization method。 The experimental results show that the Fe76Si9B10P5 glassy powder can effectively make the azo dye fade, and the fading effect is better than that of the Fe powder。 Under different experimental conditions, the degrading rate of Fe76Si9B10P5 amorphous powder was different with the fading rate of different dyes, and the fading rate of the same dye at different temperatures did not differ significantly。 In this paper, the mechanism of the fading of azo dyes by Fe76Si9B10P5 glassy powder was also discussed。 This research can help to develop new glassy alloy sewage treatment material, to achieve efficient sewage treatment, to improve the survival of the human environment, providing certain reference of experimental data, so as to realize its social value and economic value。
