Fast Degradation of Azo Dyes by Using Cu-based Metallic Glasses

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