To eliminate the long-lived minor actinide (MA) elements from high activity liquid waste (HLW), a group partitioning from a simulated HLW solution containing 14 typical elements and 3.0 M HNO3 was performed. It was done by utilizing two macroporous silica-based polymeric N,N,N,N-tetraoctyl-3-oxapentane-1,5-diamide (TODGA) and octyl(phenyl)-N,N-diisobutylcarbamoylmethylphosphine oxide (CMPO) composites (TODGA/SiO2-P and CMPO/SiO2-P)- It was found that in the first column packed with TODGA/SiO2-P, the tested elements were separated to (1) Cs, Ru, and Mo (non-sorption group), (2) minor actinides (MAs), rare earths (REs), Sr, and I'd (MA-RE-Sr-Pd group), and (3) Zr, respectively, by eluting with 3.0 M HNO3, 0-01 M HNO3, 0.05 M DTPA-pH 3.75, and 0.5 M H2C2O4 at 298 K. MA were considered to flow into MA-RE-Sr-Pd group along with Gd and Dy because of their similar sorption and elution behavior towards TODGA/SiO2-P- In the second column packed with CMPO/SiO2-P, the MA-containing effluent was separated to (1) Sr-Pd group and (2) MA-RE group, respectively by eluting with 3.0 M HNO3 and water at 323 K. MA was believed to flow into MA-RE group. Based on the results obtained, a process entitled GPEC (Group Partitioning of HLW by Extraction Chromatography) for effective partitioning of minor actinides and rare earths from HLW utilizing two macroporous silica-based polymeric composites was proposed.
