摘　　要：自行研制和组装了自动光度分析仪，结合流动注射分析（ＦＩＡ）—光度法，对水中微量铅进行测定。在９０ｓ内完成一个试样的全自动分析。采样频率为４０个样／ｈ，铅在０～４．０μｇ／ｍｌ浓度范围内符合比尔下律。该法对株州治炼厂的总排净化水和铅系统的生活废水进行了测定，结果令人满意。Based on the flow injection-spectrophotometry,an automatic photometric analyzer is designed to determine the microamount lead in industrial waste water.The analysis process including zeroing,sample loading and injecting,data reading,standard calibration,measurment of absorbance and results printing can be completed in 90s and Beer’s law is obeyed in range of 0-4.0μg/ml.The sampling frequency is 40 samples/hour.The proposed method has been aplied to the determination of lead in the waste water at Zhuzhou Smelter.The results are satisfactory.
