摘　　要：为保障铁路旅客健康、提高高铁餐饮服务品质,使用气相色谱-质谱(GC-MS)检测技术对高铁餐饮使用一次性餐盒中的邻苯二甲酸酯类(PAEs)塑化剂含量进行检测。结果表明,邻苯二甲酸酯类(PAEs)的线性范围为100~1000μg/L,相关系数r≥0.999,方法检出限0.60~1.68 mg/kg,定量下限为1.51~4.21 mg/kg,样品平均加标回收率为97%~108%,样品批内精密度为1.67%~6.38%,样品批间精密度为1.98%~7.03%。该检测方法操作简便,结果准确可靠,可用于高铁餐饮服务使用的一次性餐盒中邻苯二甲酸酯类塑化剂含量的日常测定和监测。In order to protect the health of railway passengers,improve the quality of high-speed railway catering services,so the detection method of the content of phthalic acid esters(PAEs)plasticizers in disposable lunch boxes in high-speed railway catering was researched by gas chromatography-mass spectrometry(GC-MS)detection technology.The result show that on the linear range of phthalic acid esters(PAEs)was 100~1000μg/L,the correlation coefficient was r≥0.999,the detection limit was 0.60~1.68 mg/kg,and the lower limit of quantification was 1.51~4.21 mg/kg,the average spiked recovery rate of the samples was 97%~108%,the intra-assay precision was 1.67%~6.38%,and the inter-assay precision was 1.98%~7.03%.The detection method was simple,accurate and reliable and can be used for daily determination and monitoring of phthalate plasticizers in disposable lunch boxes used in high-speed railway catering services.
