Extraction of tetravalent and hexavalent plutonium by straight and branched chained monoamides was studied using UV-Vis spectroscopy. It was determined that predominantly anionic, outer sphere species are, formed, in all instances instead of Pu4+ recovery
by acyl branched monoamides. Distribution values calculated from UV-Vis analysis were compared to tracer level LSC measurements, and were found to agree. Distribution values of hexavalent Am were also assessed. Good distribution values were achieved with straight
monoamides and bis-2-ethyl hexyl phosphoric acid.
