摘　　要：通过对不同1,1-二氟乙烯-全氟丙烯共聚物浓度的聚乙烯为载体的母粒进行离子色谱测试,确定了氟化合物和氟元素响应值之间具有线性关系,且在1,1-二氟乙烯-全氟丙烯共聚物含量低于5%的样品中,通过测试获得的线性方程具有很高的应用适应性,可以作为对塑料薄膜包装和其上下游产品中是否含有PFAS物质及其含量水平的有效测试方法。By conducting ion chromatography tests on masterbatches with different concentrations of 1,1-difluoroethylene-perfluoropropene copolymer as carriers in polyethylene,a linear relationship between the response values of fluorine compounds and fluorine elements was established.For samples with 1,1-difluoroethylene-perfluoropropene copolymer content below 5%,the linear equation obtained through testing demonstrates high applicability and can serve as an effective testing method for determining the presence and concentration levels of PFAS substances inplastic film packaging and its upstream and downstream products.
