摘要
建立了吹扫捕集/气相色谱-质谱法测定生活饮用水中苯甲醚、二溴乙烯、五氯丙烷的方法,检测方式为全扫描(SCAN),扫描离子范围是 35~270 u.经过对吹扫时间、吹扫温度、升温程序等一系列参数的优化,使目标物的峰形良好、精密度和准确度良好,并且得到较低的检出限.本方法适用于生活饮用水中苯甲醚、二溴乙烯、五氯丙烷3 种挥发性有机物的测定.
Abstract
A purge capture/gas chromatography-mass spectrometry method was established for the determination of anisole,dibromoe-thylene,and pentachloropropane in drinking water.The detection method was full scan(SCAN),with a scanning ion range of 35~270u.After optimizing a series of parameters such as blowing time,blowing temperature,and heating program,the peak shape of the target substance was good,with good precision and accuracy,and a lower detection limit was obtained.This method is applicable to the determination of three volatile organic compounds in drinking water,namely anisole,dibromoethylene,and pentachloropropane.
