SYNERGISTIC EXTRACTION OF URANIUM (VI) WITH 1,10-BIS (1'-PHENYL-3'-METHYL-5'-OXOPYRAZOLE-4'-YL) DECANEDIONE-1,10 AND 1,10-PHENANTHROLINE

Synergistic extraction of UO22+ with 1,10-bis(1'-phenyl-3'-methyl-5'-oxopyrazole-4'-yl)decane-dionel-1,10 and 1, 10-phenanthroline has been investigated. The composition of the extractive and equilibrium constant of the synergistic extraction have been determined. The solubility, molar conductance , thermal stability, UV, IR, and 1HNMR spectra of the solid extractive have been discussed. The synergistic extraction mechanism and the possible structure of the complex have been suggested.
