摘　　要：采用顶空-气质联用技术测定经0~50 kGy剂量辐照的三种PE类复合材料18种溶剂残留物的变化情况,并对其几种降解产物进行定性分析。结果表明:经过辐照,三种PE类复合材料的溶剂残留物发生变化的主要成分为酮、酯、醇类等化合物,且在辐照过程中,降解生成了18种溶剂残留目标物以外的三种新的化合物,分别是正己烷、乙醛和异戊醇。HS-GC-MS was used to determine the changes in 18 solvent residues in three PE-based composite materials irradiated with doses of 0 to 50 kGy,and qualitative analysis was performed on several degradation products.The results showed that the main components of solvent residues in the three PE-based composites changed after irradiation,including ketones,esters,alcohols,and other compounds.Additionally,three new compounds(n-hexane,acetaldehyde,and isoamyl alcohol)were generated during irradiation,which were not among the 18 targeted solvent residues.
