Simultaneous recovery of plutonium and americium from assorted analytical waste solutions using extraction chromatography

A rapid extraction chromatography based methodology was developed for simultaneous recovery of plutonium and americium from various kinds of analytical waste obtained during chemical quality control of plutonium based nuclear materials using sulphonic acid based actinide™ resin. Efforts were made to understand the effect of initial feed acidity, gamma radiation and the concentrations of Am3+ and Pu4+ on their k d. values. Processing of assorted analytical waste solutions through this method revealed that more than 95 % of Am3+ and 90 % of Pu4+ were adsorbed on the resin while iso- propanol can be successfully employed for the quantitative recovery of both the actinides from the loaded resin phase.
