摘　　要：用不溶性淀粉黄原酸酯 (ISX)处理含铜废水 ,探讨了ISX用量、反应液pH值、反应时间等因素对铜离子去除率的影响。实验表明 ,当ISX加入量为理论加入量的 1.4倍时 ,在室温搅拌反应 40min ,Cu2 +的去除率可达 97%以上 ,处理后的废水中Cu2 +浓度小于 0 .2mg L。The treatment of water containing copper ions using insoluble starch xanthate(ISX) was studied. The effect of such factors as ISX dosage, pH value of reaction liquid and reaction time on the efficiency of copper ion remaval is investigated. It is found that when the ISX dosage is 1.4 times of its theoretical dosage and the time for agitating at room temperature is 40 min, the Cu 2+ removal efficiency is up to more than 97%, and the concentration of Cu 2+ in treated waste water is below 0.2 mg/L.
