中文摘要：

研究了CU2#重金属离子捕集剂处理含铜废水的效果，结果表明：在pH1-14范围内，搅拌时间为5min，不加絮凝剂时，CU2#重金属离子捕集剂对含铜废水处理后，其上清液中铜含量可低于0.3mg·1^-1，对铜的去除率达到99．7％，一次性处理后的含铜废水即达到国家排放标准．另外，用CU2#重金属离子捕集剂对EDTA络合铜离子的处理效果进行了初步探讨。

英文摘要：

The treatment effects of heavy metal chelating agent CU2# on Cu^2＋ in the wastewater were studied in the paper. Under the optimum conditions （the range of pH value is 1-14, stirring time is 5 minutes, no flocculent is added）, the dosage of Cu^2＋ treated by heavy metal chelating agent CU2# was not more than 0.3mg·1^-1, 99. 7% Cu^2＋ was removed for wastewater, which meet the government criterion. The treatment effect of heavy metal chelating agent CU2# on Cu^2＋ chelated by calcium complex disodium salt in the wastewater and chelating mechanics of heavy metal chelating agent CU2# on Cu^2＋ were also studied.
