Synergistic Extraction of Uranium (VI) by Complexation with CYANEX-272 and CYANEX-923, TPBD, TNBD, TOPO in Presence of Nitrate
Journal Title: International Journal of Research in Chemistry and Environment (IJRCE) - Year 2012, Vol 2, Issue 2
Abstract
Synergistic extraction of uranium (VI) from nitrate medium by cyanex 272 (HA)2 along with cyanex 923, TPBD, TNBD, TOPO and their mixtures in xylene as extractants has been investigated. Analysis of the extraction data by graphical method by taking into account the complexation of the metal ion in the aqueous phase with organic ligands and all plausible complexes extracted into the organic phase is carried out. The metal ion is extracted into xylene as UO2(HA2)2. The results demonstrate that uranyl ion is extracted into xylene as UO2(HA2)2 with cyanex-272 alone and as UO2(HA2).NO3.S (where S = cyanex-923/TOPO )with cyanex-272 and cyanex-923/TOPO, and as UO2(HA2)2.S with cyanex-272 and TPBD/TNBD (where S = TPBD/TNBD). The synergistic systems enhance the extraction efficiency of uranium (VI) marginally.
