摘要
本文研究了铜─钙黄绿素流动注射荧光熄灭法测定铜的条件，此法操作简便、快速、重现性好，进样频率１２０次／ｈ，相对标准偏差小于１．５％，检测限０．０２３μｇ／ｍｌ．用于测定牛肝、山药及污水中痕量铜，结果满意。
The method is studied for the determination of trace copper using the system of copper-calcein by fIow injection fluorescence quenching.The method proposed has the advantages of conve-nience， rapidity and reliability．The relative standard deviation is less than 1. 3％ and limit of detectionis 0．023μg／ml. This method has been used for analysing liver，chinese yam and waste water.
