    • Abstract

       

      Synergism in the extraction of lanthanum, europium, lutetium, copper and thorium has been studied using a mixture ofhtta and 2,3-dimethyl, 1-phenyl pyrazol-5-one (antipyrine). Synergism was observed in all the cases except copper. The nature of extracted species has been determined on the basis of log-log plots and the equilibrium constants for the adducts have been evaluated. Antipyrine has been found to be a good donor comparable in strength to other alkylphosphorus donors.
