摘　　要：一种非掩蔽测定铜氨液中低价铜方案。用锌置换铜氨液后用EDTA滴定,计算低价铜。特点是溶液清亮,终点显明,费用低。可非氧化快速测定总铜。A method of determination of low - valence copper in cuprammine solution using non - masking way was proposed . After replacement of copper with zinc as zincammine solution which was titrated with EDTA. The low - valence copper could be calculated . The advantages of the method were solution clear, end- point acuity and low -cost. It could quickly determinate total copper by non -oxidation.
