摘要
用化学还原法制备纳米零价铁铜(nZVICu),以AO7为目标污染物,对比分析了自制nZVICu降解水中AO7的影响。结果表明,自制nZVICu对AO7有很好的降解效果。在pH=4.0和25℃的条件下,当AO7初始浓度为20 mg/L,纳米零价铁铜投加量为1.0 g/L,过硫酸盐浓度为0.5g/L时,AO7去除率高达99.2%;AO7降解率随着初始浓度的下降而显著提高,符合伪一级反应动力学。
Nano zero valent iron and copper （nZVICu） was prepared by chemical reduction method, and AO7 was used as the target pollutant. The effect of homemade nZVICu on the degradation of AO7 in water was compared and analyzed. The results show that the homemade nZVICu has a good degradation effect on AO7. Under the conditions： the pH of 4.0 ,the temperature of 25 0C, the AO7 initial concentration of 20 mg/L, the nano nZVICu dosage of 1 g/L and the persulfate concentration of 0.5g/L, the removal rate of AO7 reached up to 99.2%; the further studies found that the degradation rate of AO7 decreased with the initial concentration increased, which consistent with the pseudo first order reaction.
