Synergistic extraction of hexavalent plutonium was studied with HPMBP in combination with DBDECMP, DHDECMP or CMPO in benzene medium at various fixed temperatures. The equilibrium constants for the organic phase addition reaction (log Ks) were found to follow the trend in basicity of the neutral donors. Thermodynamic parameters were evaluated and these indicated that organic phase reaction is an addition and not a substitution reaction. Further, the bidentate donors act as monodentates.
