Jd. Navratil et al., EXTRACTION OF CS, SR, EU AND U IN 2 AQUEOUS-PHASE EXTRACTION SYSTEMS CONTAINING SODIUM-CARBONATE, Journal of radioanalytical and nuclear chemistry, 201(2), 1995, pp. 81-87
Extraction systems with two aqueous phases based on concentrated solut
ions of sodium carbonate and polyoxonium compounds (PEG 3000, Slovafol
910 and 18-crown-6) have been used for the extraction of Cs, Sr and E
u. Besides the variation of PEG and Slovafol, the effect of dicarbolly
lcobaltate anion, xylenol orange, thymolphthalexone and CDTA on fissio
n product partion has been studied.
