三-((2-(N,N-二乙基乙酰胺基)氧基)乙基)胺萃取Th的研究
Solvent Extraction Study of Thorium (Ⅳ) with Tri-((2-(N, N-Diethylacetamide)oxy)ethyl) amine
【摘要】 以三-((2-(N,N-二乙基乙酰胺基)氧基)乙基)胺为萃取剂,1,2-二氯乙烷为稀释剂,研究从硝酸-苦味酸溶液中Th(Ⅳ)的萃取行为。讨论了水相中苦味酸根浓度、萃取剂浓度对Th(Ⅳ)分配比的影响,也对萃取机理进行了初步探讨。
【Abstract】 The solvent extraction of thorium (Ⅳ) from nitrate-picric acid medium by tri-((2-(N,N-diethylacetamide)oxy)ethyl)amine in 1,2-dichloroethene were investigated at different concentration of extractants and picric acids. The mechanism of the solvent extraction is discussed on the base of the experimental results.
