气相色谱质谱联用法分析60Coγ对包装材料双向拉伸尼龙/流延聚丙烯（BOPA/CPP）的辐解行为的影响

摘要

This article researched radiolysis Behavior of 60 Coγirradiated BOPA/CPP Packaging Material by GC/MS. In full scan mode,all the 60 compounds were determined by spectrum,the mainly new radiolysis products were benzene,1,3 bis (1,1-dimethylethyl)and 2,5-Cyclohexadiene1,4-dione;At the same time,the contents of benzene,1,3,bis(1,1-di⁃methylethyl);Phenol,2,4-bis(1,1-dimethylethyl);2,5-Cyclohexadiene1,4-dione;Phenol 2,6--bis(1,1-dimethyleth⁃yl ) ,2,6-bis(1,1-dimethylethyl);Bis(cis-13-docosenamido)methane had obvious changes ,but the other radiolysis products had few changes at different irradiation intensities.%利用气相色谱质谱联用法研究了，受不同强度60Coγ辐照的包装材料BOPA/CPP的辐解行为；经过谱库检索，共检出60多种辐解产物，其中新检出主要的辐解产物有1，3-二叔丁基苯、2，6-二叔丁基苯醌；在不同的辐照强度下，1，3-二叔丁基苯，2，4二叔丁基苯酚，2，6二叔丁基对苯醌，4-乙基，2，6-二叔丁基苯酚，顺芥酸酰胺等物质发生了较明显的变化，其余辐解物没有发生太大的变化。
