| 摘 要： | 研究了在聚乙二醇辛基醚（OP）表面活性剂存在下，用紫脲酸胺指示剂络合滴定铜的方法。实验表明，在OP存在下，以紫脲酸胺作指示剂，用EDTA滴定铜，终点变色敏锐，滴定误差小，用于铜矿中铜的测定，与碘量法比较，结果满意。

| Abstract: | It's analyzed that the improvement measuring copper's acutity, when the surface active agent OP eid with the Murexide indicators in complexometric titration. Experiment proves, while using Murexide as indicators to titrate copper then adding surface active agent OP,it can improve the acutity of changing colour in the end and the accurtity of titration's analyzition.The result is satistied to measure the aopper in copper salt in the way. |
