Description

The synergistic extractions of uranium(VI) nitrate using HDEHP, PMBP (1-phenyl-3-methyl-4-benzoylpyrazolone-5) and TBP were studied for benzene media. A new method is proposed to calculate the equilibrium constants for such kinds of ternary synergistic extraction systems. The extraction reactions and their equilibrium constants were found. Models for the extraction mechanism are also discussed. (author) 8 refs.; 9 figs.; 1 tab
