| 中文摘要:采用气相色谱-质谱(GC-MS)技术建立了纺织材料及其制品中16种限用有机锡类化合物的测定方法。以甲醇和乙酸钠的混合溶液作为提取剂，对样品进行超声提取，提取液经四乙基硼酸钠衍生化后，再用正己烷进行萃取，DB-5MS (30 m×0.25 mm×0.25 μm)色谱柱分离，气相色谱-质谱选择离子模式进行分析检测，内标法定量。16种有机锡类化合物在50~500 μg/L质量浓度范围内与峰面积呈线性关系，方法的定量下限均为0.05 mg/L(0.15 mg/kg)。样品加标回收率为77.6%~106.0%，相对标准偏差(RSD，n=6) 不大于8.3%。结果表明该方法快速可靠、准确简便，适用于纺织材料及制品中有机锡类化合物的分析检测。 |

| Abstract:A gas chromatography-mass spectrometric(GC-MS) method was developed for the determination of 16 organotin compounds in textile materials and their products.Samples were ultrasonically extracted with a mixture of methanol and sodium acetate,then the extract was derived with sodium tetraethyl borate,and extracted with n-hexane.The target ingredients were separated on a DB-5MS(30 m×0.25 mm×0.25 μm) column.The 16 organotin compounds were analyzed in selective ion mode(SIM).Under the optimal conditions,the calibration curves for 16 organotin compounds were linear in the range of 50-500 μg/L,with limit of quantitation of 0.05 mg/L(0.15 mg/kg).The recoveries ranged from 77.6%to 106.0%,with relative standard deviations(RSDs,n=6) not more than 8.3%.This method was rapid,reliable,accurate and convenient to operate,and it was appropriate for the determination of organotin compounds in textile materials and their products in routine tests. |
