摘要

建立了C18膜萃取/液相色谱-质谱联用技术测定极地水体中10种有机磷酸酯(OPEs)的方法。根据优化后的样品前处理及仪器方法，利用C18膜富集4 L水体中的10种OPEs，经二氯甲烷超声提取，在电喷雾正离子模式下，采用选择反应监测(SRM)模式进行分析，线性相关系数为0994 4~0.999 9。10种OPEs的加标回收率为64.1%~115% ，方法检出限为0.08~0.55 ng/L。该方法适用于极地水体中10种OPEs的分析，利用该方法对北极水体样品中的10种OPEs进行检测，测得冰川融水中∑OPEs的质量浓度为0.64~6.64 ng/L，海水中∑OPEs的质量浓度为0.09~2.03 ng/L。

Abstract

A rapid method was developed for the determination of 10 organophosphate esters(OPEs) in the Arctic waters by liquid chromatography-mass spectrometry(LC-MS/MS) combined with C18membrane disk extraction.By the optimized pretreatment and instrumental methods,10 OPEs were collected with C18membrane disk from 4 L water,and extracted with dichloromethane in ultrasonic extraction apparatus.After purification and concentration,the OPEs were analyzed by LC-MS/MS under positive electrospray ionization in selective reaction monitoring(SRM) mode.The linear correlation coefficients are in the range of 0.994 4-0.999 9.The recoveries of 10 OPEs in water samples ranged from 64.1% to 115% with the method detection limits of 0.08-0.55 ng/L.Furthermore,10 OPEs compounds in the Arctic waters samples were analyzed by this method,and the OPEs concentrations in the river and seawater were in the ranges of 0.64-6.64 ng/L and 0.09-2.03 ng/L,respectively.
