流动注射化学发光法在线检测饮用水中的3-硝基丙酸
On-l ine determination of emergency pol lution of 3-nitropropionic acid in drinking water by flow injection chemi luminescence
摘要
Abstract
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 ~ 1 50 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 appli-cation in rapid detection and alarm of emergency pollution of 3-nitro-propionic acid in drinking water.关键词
