摘　　要：为了降解饮用水中2-溴乙酰胺(MBAcAm),采用Fe/Cu催化还原的方法去除饮用水中的MBAcAm,考察Fe/Cu质量比、Fe/Cu投加量、温度和MBAcAm初始浓度对Fe/Cu催化还原降解MBAcAm的影响。结果表明:Fe/Cu催化还原技术对MBAcAm的去除效果优于单质铁还原技术,Fe/Cu混合物质量比为10时,去除效果是单质铁的1.56倍;Fe/Cu混合物的投加量增加有助于MBAcAm的去除;提高温度有助于去除溶液中的MBAcAm;MBAcAm的去除总体上随MBAcAm初始浓度的增大而增大。Fe/Cu催化还原技术去除MBAcAm的反应过程符合一级动力学规律。Fe/Cu catalyst was utilized for reductive degradation of monobromoacetamide(MBAcAm)in drinking water.The influences of Fe/Cu mass ratio,Fe/Cu dosage,temperature and initial concentration of MBAcAm on the reductive degradation of MBAcAm were investigated.The results showed that the removal efficiency of MBAcAm by Fe/Cu catalysts was better than that by single iron catalyst.When the mass ratio of Fe/Cu was 10,the removal efficiency was 1.56 times of that of single iron.Increasing the dosage of Fe/Cu or the temperature could both benefit the removal of MBAcAm.The removal efficiency of MBAcAm generally increases with the initial concentration of MBAcAm.The reductive degradation of MBAcAm by Fe/Cu catalyst accords with the first-order kinetics.
