摘要
研究了新型酰胺萃取剂N-辛酰-2-甲基哌啶烷(OMPPD)在硝酸介质中萃取铀(VI)的辐照性能,考察了γ射线剂量以及在不同的酸度和稀释剂中γ射线对萃取铀(VI)分配比的影响,发现OMPPD比磷酸三丁酯(TBP)具有较好的耐辐照性能。
N-octanoyl—2-methylpiperidine (OMPPD) a novel amide type extractant for the extraction of U (VI) from aqueous nitric acid medium, was studied for γ-ray irradiation effect. The effects of radiation dose, concentration of nitric acid and diluent on the distribution ratio for the extraction of U (VI) were studied. It is found that OMPPD has better radiation stability compared with Tributyl phosphate (TBP).
