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) decanedione-1, 1- 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
