Revised Date: 17 May 1995

The synergistic extraction of uranitim(Ⅵ) by a ternary system composed of 4,4'-decanedioyl-bis-(1-phenyl-3-methyl-5-pyrazolone), trioctylphosphine oxide (TOPO) and pyridine was studied. The composition of the extracted compound in solution was determined using the slope method. The extracted solid termary complex was characterized by means of elemental analysis,IR and ¹H NMR preliminarily.
