摘　　要：采用反相流动注射光度分析技术，以能形成颜色相近产物的化学反应为基础，建立了工业废水中Ｎｉ和Ｃｕ的连续测定方法和装置。测定频率６０样／ｈ，Ｎｉ和Ｃｕ的最低检出浓度分别为０．０３μｇ／ｍｌ和０．０４μｇ／ｍｌ。The new wastewater monitoring system by use of reversed flow injection spectrophotometry has been developed with injection of different reagents to prepuce similar color compounds by chemical reactions.The system has been used to simultaneous determination of nickel and copper in wastewater.The detection freqency of the method is 60 sampels h-1,the minimum detection limits are 0.03μg Ni ml-1 and 0.04μg Cu ml-1 respectively.
