【摘要】 用气相色谱-电子捕获负化学离子源-质谱法（GC-ECNI-MS）对纺织品中的氯化松节油进行定性和定量分析。通过对分子离子峰和脱氯离子峰的加和与浓度之间的关系转化，实现对氯化松节油的定量分析。对纺织品常用棉贴衬布样品进行加标试验，回收率和相对标准偏差分别在83.55%～95.73%和2.81%～4.10%，定量限为0.2 mg/kg，符合日常检测要求。对10个实际样品进行检测，未发现氯化松节油残留。本研究确定的检测氯化松节油的方法具有前处理简单、灵敏度高和回收率高的优点，为生态纺织品标准中氯化松节油的检测提供了技术支持。更多还原

【Abstract】 Qualitative and quantitative analysis of chlorinated turpentine in textiles was applied by GC-ECNI-MS method. The quantitative analysis of chlorinated turpentine was realized by transforming the relationship between the sum of molecular ion peak and dechlorination ion peak and the concentration. The standard addition experiment was conducted on the cotton cloth samples commonly used in textiles. The recovery rate and relative standard deviation were in the range of 83.55%～95.73% and 2.81%～4.10%, respectively, and the limit of quantification was 0.2 mg/kg,which meet the requirements of daily testing. Ten actual samples were tested, and no residue of chlorinated turpentine was found. Due to the advantages of simple pretreatment, high sensitivity and high recovery rate, the detection method in this study can provide technical support for the detection of chlorinated turpentine in the textiles.更多还原
