| 摘 要： | 构建了气相色谱-质谱(GC-MS)测定纺织品中二辛基锡的方法。应用液液萃取法提取纺织品中的二辛基锡,通过四乙基硼化钠衍生后,使用用GC-MS总离子流图和选择离子进行定性检测,使用选择离子的质谱峰进行定量测定。该方法样品前处理简单,使用外标标准曲线法对二辛基锡检测,在0.3～2.0μg/mL范围内呈良好的线性关系,加标回收率在93.1%～102.4%之间,可应用于纺织品中有机锡的检测。

| Abstract: | A simple method for the determination of dioctyhin （DOT） in textile samples was developed with gas chromatography - mass spectrometry （ GC - MS）. DOT was extracted by liquid - liquid extraction and further derivatized with NaBEt4. Then the ethyl organotin was analyzed by GC -MS in the selected ion mode. The qualitative and quantitative analysis was carried out with the selected ion chromatograms obtained. Under the selected conditions, a good linearity range was got from 0.3 -2.0 μg/mL with the average recoveries in the range from 93.1% - 102.4%. The proposed method was further applied to the textile samples detection. |
