摘　　要：采用高级氧化法,以Cu_(46)Zr_(44.5)Al_(7.5)Y_(2)非晶合金为催化剂活化过硫酸钠(PS)降解水中的酸性橙,考察了溶液初始pH值、Cu_(46)Zr_(44.5)Al_(7.5)Y_(2)非晶合金用量、PS初始浓度、温度对降解的影响,以及重复使用过程中的稳定性.结果表明,Cu_(46)Zr_(44.5)Al_(7.5)Y_(2)非晶合金活化过硫酸钠可以显著地降解水中酸性橙,在初始pH值为5,Cu_(46)Zr_(44.5)Al_(7.5)Y_(2)非晶合金用量为0.5 g/L,PS初始浓度为0.5 mmol/L,温度为25℃的最佳条件下反应50 min,酸性橙的降解率能够达到91.2%,并且Cu_(46)Zr_(44.5)Al_(7.5)Y_(2)非晶合金在重复使用10次后的降解率仍能达到85.3%.An effective advanced oxidation process for the degradation of acid orange in water was reported.This method was based on the oxidation of acid orange by Cu_(46)Zr_(44.5)Al_(7.5)Y_(2) amorphous alloy activated sodium persulfate(PS).The effects of the initial pH value of solution,the dosage of Cu-based amorphous alloy,the initial concentration of PS and the temperature on the degradation were examined,as well as the stability in the recycling process.The results show that acid orange can be degraded significantly in Cu_(46)Zr_(44.5)Al_(7.5)Y_(2) amorphous alloy AC/PS system under the optimal conditions of the initial pH value of 5,the dosage of Cu_(46)Zr_(44.5)Al_(7.5)Y_(2) amorphous alloy of 0.5 g/L,the initial PS concentration of 0.5 mmol/L and the temperature of 25℃for 50 min,and the removal rate of acid orange can reach 91.2%.Moreover,the degradation rate retains at 85.3%after the Cu_(46)Zr_(44.5)Al_(7.5)Y_(2) amorphous alloy has been used ten times.
