Abstract

The third-phase formation in the DHDECMP-dodecane-HNO3 system during the actinides extraction was investigated based on the densities of the phases formed and the acid uptake by the DHDECMP phase. The effects of various parameters like nature of acids, diluents, temperature of extraction, acid molarity, and concentration of DHDECMP on the Third-phase formation were studied. The third-phase formation was also explained on the basis of results of small-angle neutron scattering studies (SANS).
