摘　　要：建立了加速溶剂萃取-气相色谱/质谱联用法（ASE-GC/MS）用于检测塑料中5种氯烃类化合物的含量,并比较了萃取方法、萃取溶剂及萃取温度对萃取效果的影响。结果表明：5种氯烃类化合物的质量浓度在1.0-25.0mg/L范围内分别与其对应的峰面积呈线性关系,测定下限（10倍信噪比）均为1.0 mg/kg;另外,在1.00、5.00、10.00 mg/kg 3个添加浓度水平下,5种氯烃类化合物的回收率在83.2%~101.2%之间,相对标准偏差（RSD）小于5%。该方法准确度高,精密度好,能够满足实际检测需求。A new method was established for determination of five kinds of chlorohydrocarbon compounds in plastics by accelerated solvent extraction technique combining with GC/MS method.The effects of extraction method,solvent and operating temperature on the extraction efficiency were investigated.The results show that： the mass concentrations of five kinds of chlorohydrocarbon compounds have linear relationship with values of peak area in the range of 1.0~25.0 mg/L,and the detection limit（S/N=10） are all for 1.0 mg/kg.Test of recovery was determined by using standard addition method at three concentration levels of 1.00,5.00,10.00 mg/kg respectively,and the recovery rates of five chlorohydrocarbon compounds are up to 83.2%~101.2% with the relative standard deviations（RSD） less than 5%.This method is accurate,precise,and meets the actual detection need.
