Abstract
Extraction of U(VI) by mixtures of 2-ethylhexyl 2-ethylhexylphosphonic acid (PC88A) and TOPO in cyclohexane and xylene from aqueous sulfuric acid medium has been investigated. Synergism was observed and the spe cies responsible was identified as UO2H2Y4.TOPO. From the data equilib rium constants for the various reaction equilibria at different temper atures and the thermodynamic parameters were calculated. Antagonism wa s observed when alkylamide or TBP was used as the neutral donor.
