摘　　要：对新型重金属螯合剂EX2000处理酸性含铜废水进行了研究,探讨了EX2000的用量、搅拌时间、沉降时间等因素对铜离子去除率的影响。结果表明,在EX2000投加量为15 mL、室温下搅拌10 min、沉降25 min的条件下,铜离子去除率最高、达99.41%,处理后废水中铜离子的质量浓度为0.038 mg/L,远远低于国家排放标准(0.5 mg/L)。Treatment of wastewater containing copper ions by the novel heavy metal chelating agent EX2000 have been studied.The effects of EX2000 dosage,stirring time and settling time on the efficiency of copper ion-removal have been investigated.The optimum conditions had been determined that EX2000 dosage was 15 mL,stirring time was 10 min at room temperature and settling time was 25 min.Under the optimum conditions,the removal efficiency of Cu2＋ could reached to 99.41%,and the concentration of Cu2＋ in treated wastewater was below 0.038 mg/L.It meet national emission standards（0.5 mg/L）.
