摘　　要：通过气相色谱-质谱法对纺织品中可能存在的17种有机锡化合物进行检测分析,采用四乙基硼化钠衍生化试剂能将氯化有机锡转化为有机锡化合物,然后通过内标法来定量。对纺织品中常用的贴衬布样品进行加标试验,回收率和相对标准偏差分别在81.25%~102.84%和3.09%~8.18%,定量限为0.2 mg/kg,符合日常检测要求。该研究确定的内标法检测纺织品中17种有机锡化合物的方法,可为相关检测试验室提供技术支持和帮助。17 types of organotin compounds that may exist in textiles were analyzed and detected by gas chro-matography-mass spectrometry.Using the sodium tetraethylboridederivatization reagent,the organotin chloride can be converted into organotin compounds,and the internal standard method was adopted to quantify.The standard addi-tion experiment was carried out on the samples of interlining cloth,the recovery rate and relative standard deviation were in the range of 81.25%~102.84%and 3.09%~8.18%,respectively.The limit of quantification was 0.2 mg/kg,which can meet the requirements of daily testing.The internal standard method established in this study for the detection of 17 types of organotin in textiles can provide technical support to the related testing laboratories.
