摘要
以三-((2-(N,N-二乙基乙酰胺基)氧基)乙基)胺为萃取剂,用1,2-二氯乙烷做稀释剂,在苦味酸-硝酸介质中对U(Ⅵ)萃取,主要研究了稀释剂对萃取效率的影响,萃取剂浓度、苦味酸根浓度对U(Ⅵ)分配比的影响。
The solvent extraction of uranium (Ⅵ) from nitrate-picric acid medium by tri-((2-(N,N-Di-ethylacetamide)oxy)ethyl)amine in 1,2-dichloroethene were investigated at different concentration of ex-tractants and picric acids. The mechanism of the solvent extraction is discussed on the base of the experimental results.
