Abstract

The extraction of UO 2+2 from nitrate solution has been carried out using DHDECMP. Different parameters affecting the distribution coefficient of UO 2+2 have been determined. The extraction of UO 2+2 was found to have second order dependency on both extractant and H+ concentrations. Addition of some bases as TBP and TOPO to the phosphonate extractant increased the distribution of UO 2+2 to a great extent. LogD for UO 2+2 with respect to both synergistic bases was found to be a first order dependent. The thermodynamic parameters have been calculated and the extraction mechanisms have been suggested.
