摘　　要：利用碱性条件下3-硝基丙酸对鲁米诺—高锰酸钾化学发光体系有显著的抑制作用,结合流动注射分析技术,建立了一种在线检测饮用水中3-硝基丙酸的流动注射化学发光新方法。在优化的试验条件下,其线性范围为1-150mg/L,方法的检出限为0.28 mg/L,相对标准偏差为1.9%,3-硝基丙酸加标回收率为76.5%~93.8%。该方法具有较好的准确性和选取性,可实现饮用水中3-硝基丙酸的快速在线检测。On the basis of inhibition of chemiluminescence reaction of luminol and potassium permanganate in sodium hydroxide medium by 3 nitropropionic acid, a novel flow-injection chemiluminescence method for determination of 3-nitropropionic acid in drinking water was developed. A linear range for 3-nitropropionic acid determination was 1- 150 mg/L. The detection limit of 3-nitropropionic acid was 0.28 mg/L and relative standard deviation （RSD） was 1.9%, with the recovery of 76.5% - 93.8%. This online determination system showed a good accuracy and selectivity and has great potential application in rapid detection and alarm of emergency pollution of 3-nitropropionic acid in drinking water.
