N,N,N’,N’-四丁基-3-氧-戊二酰胺(TBOPDA)是一种新合成的萃取剂,它可以在高酸度情况下萃取铀等锕系元素,在高废液的萃取处理中具有良好的应用前景。曾有报道采用GC方法分析辐照后的气相产物,本文采用固相微萃取技术萃取TBOPDA部分挥发性和半挥发性液相辐照产物,结合GC-MS进行鉴定,确定了其液相辐照产物主要为二丁胺、二正丁基甲酰胺、二正丁基乙酰胺。结果表明这是一种简便、快速、可靠的分析方法,具有较高的分析灵敏度。
N, N, N ’, N’-tetrabutyl-3-oxopentanediamide (TBOPDA) is a newly synthesized extractant which can extract actinides such as uranium under high acidity conditions. Liquid extraction process has a good application prospects. It has been reported using GC method to analyze the gas phase after irradiation. In this paper, some volatile and semi-volatile liquid radiation products of TBOPDA were extracted by solid-phase microextraction and identified by GC-MS. The liquid phase irradiation The main products are dibutylamine, di-n-butylformamide, di-n-butylacetamide. The results show that this is a simple, rapid and reliable analytical method with high analytical sensitivity.
