研究了新型酰胺萃取剂N-癸酰基吗啡啉(DMPHL)在硝酸介质中萃取U(Ⅵ)的辐照性能,考察了γ射线剂量以及不同的酸度和稀释剂中γ射线对萃取U(Ⅵ)分配比的影响,结果发现,DMPLH比TBP具有较好的耐辐照性能,且共辐照降解产物对U(Ⅵ)的萃取能力较弱。
The radiation stability of N-decanoylmorpholine used as novel extractant for U(VI) from aqueous nitric acid medium was studied for the first time. The effects of radiation dose?concentration of nitric acid and diluente on the distribution ratio of U(VI) were discussed. It was founded that DMPHL has better radiation stability compared with TBP and the extraction abilities of the radiolytic products for U(VI) were lowered than DMPHL.
