摘要
采用带有顶空进样器的气相色谱仪 ,分析聚苯乙烯餐具中残留苯乙烯单体量 ;以校准曲线法进行定量测定 ;在选定的色谱条件下 ,测定苯乙烯含量的线性范围为 5 .0— 10 0 0 mg/ L,检出限小于 0 .1mg/ L;本方法操作简便、快速、结果准确 ,适应于残留苯乙烯单体含量的测定。
Residues of styrene in polystyrene tableware were analyzed by headspace gas chromatography. The standard curve was used for quantitative determination. Under the selected conditions the contents of styrene are linearly related to their peak areas in the range of 5.0-1000mg/L.The detection limit is lower then 0.1mg/L. The method is convenient, rapid and the results are well repeatable.
