to their potential harms to natural environment and human health. The present study
described the degrading ability of the as-synthesized crystalline Al-Cu alloys for removal of
high-concentration Acid Scarlet 3R in alkaline aqueous solutions and its degradation
mechanism. Al-Cu alloy particles with Al/Cu ratios 19: 1 were successfully synthesized by
high-energy mechanical milling. Characterization results showed that 10 h mechanical …
