摘 要:本文介绍了染料产品中含氯苯酚的定量测定方法。采用乙酸酐乙酰化衍生的方法处理染料产品中的2,3,5,6-四氯苯酚和五氯苯酚,用DB-5MS毛细管色谱柱进行分离,气相色谱-质谱联用仪进行定性分析,外标法定量。对方法的准确度、精密度进行了测定。本方法对目标化合物的检测限可达到0.1 mg/kg,回收率在90%~100%之间。A quantitative determination method for chlorinated phenols in dye products was introduced.2,3,5,6-Tetrachlorophenol and pentachlorophenol in dye products were acetylated by acetic anhydride,and the derivatives were separated by DB-5MS capillary column,then they were qualified by GC-MS and quantified by external standard method.The accuracy and precision of the method were determined.The detection limit of the test was 0.1 mg/kg for target compounds,average recoveries ranging from 90.0% to 100%.
