介绍应用气相色谱-质谱法测定纺织品、皮革及其制品中防霉剂五氯苯酚的残留量,试样经硫酸溶液酸化后用正己烷提取,用气相色谱-质谱选择离子测定。方法简便、快速、灵敏,检出限20μg/kg,添加回收率86.7%~93.1%,变异系数4.1%~5.9%。
This article describes the determination of pentachlorophenol residues in textiles, leather and their products by gas chromatography - mass spectrometry. The samples were acidified with sulfuric acid solution and extracted with n-hexane, and determined by gas chromatography-mass spectrometry. The method was simple, rapid and sensitive. The detection limit was 20μg / kg. The recovery rate was 86.7% -93.1%, and the coefficient of variation was 4.1% -5.9%.
