顶空-气相色谱-质谱法测定丙烯腈-丁二烯-苯乙烯玩具中丙烯腈单体的含量
Determination of Acrylonitrile in Acrylonitrile-Butadiene-Styrene (ABS) Toys by Headspace-GC-MS
摘 要
提出了顶空-气相色谱-质谱法测定丙烯腈-丁二烯-苯乙烯(ABS)玩具中丙烯腈单体的含量。样品经N,N-二甲基甲酰胺溶解,在顶空进样器恒温进样,采用HP-INNO Wax极性柱进行分离,质谱中以m/z 53作为目标离子,外标法进行定量。丙烯腈单体的质量在1.00~40.0 μg的范围内线性良好,检出限(3S/N)为0.4 mg·kg-1。方法应用于ABS玩具样品的分析,加标回收率在78.0%~116%之间,测定值的相对标准偏差(n=6)在2.6%~7.9%之间。

Abstract
A method of Headspace-GC-MS was proposed for the determination of acrylonitrile in acrylonitrile-butadiene-styrene (ABS) toys. The sample was dissolved in N,N-dimethyl formamide, then injected isothermally with the headspace sampler, and separated on a HP-INNO Wax polar column. The target ion with m/z 53 was selected in MS detection. External standard method was used for quantification. The linearity range of the mass of acrylonitrile was 1.00-40.0 μg with detection limits of 0.4 mg· kg-1. The method was used for analysis of ABS toys samples, giving recovery rates measured by standard addition method of 78.0%-116%, with RSD′s (n=6) in the range of 2.6%-7.9%.
