建立了检测食品接触材料——纸、纸板、木材和木制品中含氯酚（CPs）残留量的气相色谱-质谱（GC-MS）分析方法。采用加速溶剂萃取（ASE）法为样品前处理手段，优化了萃取溶剂、萃取温度、静态萃取时间、冲洗体积和萃取循环次数等实验参数。优化结果为：以二氯甲烷为萃取溶剂，萃取温度为150 ℃，静态萃取时间为10 min，冲洗体积为(占萃取罐体积的)60%，萃取循环次数为1次。结果表明：6种CPs在0.05~2.0 μg/mL质量浓度范围内具有良好的线性关系（R＞0.99）；平均回收率在86.8%~108.8%之间（n=6）；〖JP3〗相对标准偏差（RSD）为1.8%~14.2%(n=6)；方法的检测限为0.01 mg/kg。研究表明该方法高效、简便、快捷、灵敏、准确可靠，可用于实际样品的CPs残留量的监测。

A new analytical method was developed for the determination of CPs in paper, paperboard, wood and wood products used as food contact materials by accelerated solvent extraction (ASE) and gas chromatography-mass spectrometry (GC-MS). The operational parameters of ASE, such as extraction solvent, extraction temperature, static extraction time, flush volume and extraction cycles, were optimized. The optimized procedure was using dichloromethane as extraction solvent, 150 ℃ of extraction temperature, 10 min of static extraction time, and 60% flush volume; the extraction recoveries of 6 CPs were nearly to 100% for only one cycle. The results indicated that the developed method has good linearity (R＞0.99) in 0.05~2.0 μg/mL mass concentration, good recoveries (86.8%~108.8%) and precision (relative standard deviation (RSD) 1.8%~14.2% ); the limited of detection (LOD) of the 6 CPs are 0.01 mg/kg. It was concluded that the developed method is efficient, simple, rapid, sensitive, accurate and reliable, which can be utilized for CPs residual inspection of sample.
