Abstract

The synergic extraction of uranyl nitrate from chloroform media with 1-phenyl-3-methyl-4-benzoyl-pyrazonole-5 /PMBP/, tributylphosphate /TBP/ and thenoyltrifluorylacetone /TTA/ was studied. It was found that synergic effect occurs during the extraction of uranyl nitrate with the chloroform solution of PMBP-TTA-TBP. The formation of the ternary extracted complex UO2AA'B was confirmed by the usual slope method. A method was proposed for the calculation of the ternary equilibrium constant which was evaluated to be 1gK111=2.65. Also the binary synergic extractions of uranyl nitrate with PMBP-TBP and TTA-TBP were studied. The binary equilibrium constants were found to be 1gK201=3.07 and 1gK021=1.39, respectively. An attempt has been made to interpret the data mainly on the basis of statistical factor.
