Abstract
Synergistic extraction of hexavalent plutonium was studied with HPMBP in combination with DBDECMP, DHDECMP or CMPO in benzene medium at vari ous fixed temperatures. The equilibrium constants for the organic phas e addition reaction (log Ks) were found to follow the trend in basicit y of the neutral donors. Thermodynamic parameters were evaluated and t hese indicated that organic phase reaction is an addition and not a su bstitution reaction. Further, the bidentate donors act as monodentates .
