摘　　要：饮用水消毒对病原微生物的预防起到至关重要的作用,但是有毒有害消毒副产物的产生,对人类健康造成潜在威胁.cis-2-丁烯-1,4-二醛(BDA)是近年检出的新型消毒副产物,生物毒性强,具有严重的潜在危害.本文建立了BDA的高效液相色谱-串联质谱的分析方法,旨在定量筛查出水体中的BDA.结果表明:BDA的纯溶剂标准曲线和基质匹配标准曲线的线性较好,相关系数(R^(2))均大于0.99.方法检出限为0.035μmol·L^(−1),定量限值为0.105μmol·L^(−1).回收率在83.6%‒112%之间,相对标准偏差小于10%(n=7).该方法能够快速高效地完成水体中BDA的分析.Disinfection plays a crucial role in prevention of pathogenic microorganisms in drinking water.However,the formation of toxic disinfection by-products posed a potential threat to human health.An emerging disinfection by-product,cis-2-butene-1,4-dialdehyde(BDA),possesses strong biological toxicity and serious potential hazards.This study established an analytical method for BDA by using high-performance liquid chromatography-tandem mass spectrometry(HPLCMS/MS),which aimed to screen and quantify BDA in water.The results showed that the linearity of standard curves in both pure water and matrix-match solution were good,with the correlation coefficients(R^(2))higher than 0.99.The detection limit of the method was 0.035μmol·L^(−1),and the quantification limit was 0.105μmol·L^(−1).The recovery rate ranged from 83.6%to 112%,and the relative standard deviation was less than 10%(n=7).This method is able to accomplish quick and efficient analysis of BDA in water.
