| 摘 要： | 提出了气相色谱-质谱法测定木制品中双三丁基氧化锡(TBTO)含量的方法。样品经甲醇提取,所得提取液用四乙基硼化钠衍生化,产物用气相色谱-质谱法测定,外标法定量。双三丁基氧化锡的质量浓度在0.1～40 mg.L-1范围内与峰面积呈线性关系,方法的检出限(3S/N)为0.05mg.kg-1。在3个标准加入水平下进行了回收率和精密度试验,加标回收率在88.4%～90.4%之间,相对标准偏差(n=6)在2.0%～5.4%之间。

| Abstract: | GC-MS method was applied to the determinations of bis(tributyltin)oxide(TBTO) in woodwork.The sample was extracted with methanol,the extract obtained was derived with NaB(Et)4.The product was used for GC-MS analysis.External standard calibration was adopted in the determination.Linear relationship between peak areas and mass concentrations of TBTO was obtained in the range of 0.1-40 mg·L-1.Detection limit(3S/N) of the method was 0.05 mg·kg-1.Tests for recovery and precision were made by standard addition method at 3 different concentration levels,values of recovery and RSD′s(n=6) found were in the ranges of 88.4%-90.4% and 2.0%-5.4%. |
