Abstract

The kinetic studies on the recovery of UO22+ and Pb2+ from aqueous solutions into chloroform solution of N,N’-ethylenebis(4-butanoyl-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-oneimine) schiff base H2BuEtP has been investigated and the rate of reaction found to be first order with respect to both metal ions (UO22+ and Pb2+). The rate of extraction was equally dependent on the inverse of hydrogen ion concentration for both metal ions. The rate constant Kf was equally calculated from intercepts of plots to be 0.491min-1 for UO22+ and 0.411 min-1 Pb2+ metal ions. Optimum percentage extraction of 99.714% was observed for Pb2+ metal ion at 30mins equilibration time and 98.216% for UO22+ metal ion at 20mins equilibration time. The study on mechanism of extraction for the metal ions from the aqueous phase into the organic phase showed that the formation of the first chelate ring of mono-pyrazolonato metal complex is the rate determining step which involved a slow bond-weaking effect by the bidendate H2BuEtP on the water molecule.
