本文建立了水溶性纺织助染剂中12种氯化甲苯化合物的气相色谱-质谱(GC-MS)测定方法。采用超声萃取法,以正己烷为溶剂分两次提取待测物,用DB-17MS为检测色谱柱气质联用法程序升温方式进行测定,外标法定量。结果表明该方法对12种氯化甲苯化合物的回收率为81.9%~105.6%,方法检测限可达9.8~21.6?g/kg。该法检测限低,准确可靠,适用于水溶性纺织助染剂中氯化甲苯化合物的分析监测。
本文建立瞭水溶性紡織助染劑中12種氯化甲苯化閤物的氣相色譜-質譜(GC-MS)測定方法。採用超聲萃取法,以正己烷為溶劑分兩次提取待測物,用DB-17MS為檢測色譜柱氣質聯用法程序升溫方式進行測定,外標法定量。結果錶明該方法對12種氯化甲苯化閤物的迴收率為81.9%~105.6%,方法檢測限可達9.8~21.6?g/kg。該法檢測限低,準確可靠,適用于水溶性紡織助染劑中氯化甲苯化閤物的分析鑑測。

A testing method for determination of twelve chlorinated toluenes in water-soluble textile dyeing auxiliary with GC-MS was established. With ultrasonic-assisted the sample was extracted twice by n-hexane.Then the extract was analyzed with DB-17MS by the temperature programming mode of GC-MS and was tested by external standard method. The results showed that with this method satisfactory recoveries 81.9%~105.6% and method detection limits 9.8~21.6 *g/kg could be obtained. The method features low detection limits and good accuracy, and could be used for handling water-soluble textile dyeing auxiliary samples.
