【摘要】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。更多还原

【Abstract】 This article researched radiolysis Behavior of 60 Coγ irradiated 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-dimethylethyl);Phenol,2,4-bis(1,1-dimethylethyl);2,5-Cyclohexadiene1,4-dione;Phenol 2,6--bis(1,1-dimethylethyl),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.更多还原
