STUDY ON EXTRACTION OF U(Ⅵ) WITH α-SULFINYL-N,N-DIBUTYLACETAMIDE

New extractants, α sulfinyl N,N dibutylacetamides, are synthesized. Study of extraction of U(Ⅵ) with these compounds is performed by selecting diluents, changing the concentrations of the nitric acid and extractants and salting out agent in the aqueous phase. The abilities of all compounds synthesized for extraction of U(Ⅵ) are compared to TBP. The results show that all these compounds can efficiently extract UO 2 2+ from nitric acid. With substituents 2 ethylhexyl and n butyl, the abilities of extraction of U(Ⅵ) are better than TBP.
