As a part of developing extraction chromatography technology for minor actinides (MA(III); Am and Cm) recovery from spent fast reactor fuels, improvement on the TODGA/SiO-P adsorbent to enhance its desorption efficiency was carried out. Batchwise adsorption/elution experiments revealed that 20wt% of the adsorbent concentration impregnated and 10% of cross linkage of polymer gave better desorption ratio than the reference adsorbent. Inactive column separation experiments with the simulated high level liquid waste and the optimized adsorbent revealed that decontamination factors of fission products can also be improved as well as the recovery yields.
