【摘要】 建立了涂料中6种常见邻苯二甲酸酯类化合物的GC-MS测定方法。以正己烷为萃取溶剂超声萃取涂料中的邻苯二甲酸酯类化合物,采用气相色谱-质谱(GC-MS)的选择离子检测方式(SIM)进行检测。6种邻苯二甲酸酯的线性相关系数r>0.99,回收率在83%～107%之间,相对标准偏差(RSD)为3.9%～8.4%。方法简便、快速,适合于涂料中邻苯二甲酸酯类化合物的测定。更多还原

【Abstract】 A simple and rapid method for the determination of six phthalate acid esters in coatings by GC-MS was de-veloped.Phthalate acid esters in coatings were extracted by ultrasonic extraction with hexane as the solvent,and then the ex-tracts were tested by the Selective Ion Monitoring Mode of GC-MS.The regression coefficients(r) of six phthalate acid esters were over 0.99.The recoveries varied 83%~107%.The relative standard deviations(RSDs) ranged 3.9%~ 8.4%.The method was suitable for determining phthalate acid esters in coatings.更多还原
