摘　　要：采用FLA技术,以光度比色法为基础,建立了工业废水中微量Cu^(2+)和CN^-的顺序自动分析方法和装置。其对二种离子的测定频率为60样/h,相对标准偏差<1.0％,工作曲线的r值≥0.9999,各项分析技术指标均优于手工法操作。A flow-injection system is described for the sequential spectrophotometric determination of Cu2+ and CN- ions in wastewater. The analysis frequence is 60 h-1, relative standard deviation is less than 1. 0%, and relation coefficient value for the working curve is larger than 0. 9999. The technical indices of the method proposed are superior than those of the batch method. The excellent results have been got in analysis of real sample.
