Wastewater containing azo dye has become a main harm in water pollution. Therefore, development of environment friendly materials with efficient purifying capacity seized more and more attention of people devoting to dye wastewater processing. On the other hand, advancement of metallic glasses in degrading organic water contaminant has also received wide concern. Cu-based amorphous alloy has excellent corrosion resistance and good stability in the process of degradation of azo dyes In the present thesis, single roller melt-spinning method Cu-Zr-Al-Y metallic glasses is applied so as to investigate degradation of azo dye Direct Blue in acid and alkaline solution. It is concluded that when the value of it is 2, 25μm ~ 30μm thick stripes of non-crystalline structures will be formed. With variation of the pH, rate of degradation will also change. The degradation rate in acidic solution is higher than that in alkaline and neutral solution. This is due to the fact that Azo bond and Cu-based amorphous alloy in dye molecule requires quite low activation energy to react, which makes degradation easier to proceed and thus macroscopic decoloration is also quickened. After the treatment of wastewater, white corrosion products will be produced on the surface of amorphous strip. It will affect the degradation effect.
