                      chromatography using a minimal organic solvent and compact
                      equipment to separate minor actinides such as Am and Cm from
                      nitrate acidic high-level waste (HLW) solution, several
                      novel silica-based extraction resins have been prepared by
                      impregnating organic extractants into the
                      styrene-divinylbenzene copolymer, which is immobilized in
                      porous silica particles (SiO2-P). The extractants include
                      octyl(phenyl)-N, N-diisobutylcarbamoylmethylphosphine oxide
                      (CMPO), di(2-ethylhexyl)phosphoric acid (HDEHP), and
                      bis(2,4,4-trimethylpentyl)dithiophosphinic acid (Cyanex
                      301). Compared to conventional polymer-matrix resins, these
                      new types of extraction resin are characterized by rapid
                      kinetics and significantly low pressure loss in a packed
                      column.The results of separation experiments revealed that
                      trivalent actinides and lanthanides can be separated from
                      other fission products, such as Cs, Sr, and Ru in simulated
                      HLW solution containing concentrated nitric acid by
                      extraction chromatography using a CMPO/SiO2-P resin-packed
                      column. Satisfactory separation between Am(III) and a macro
                      amount of lanthanides from simulated HLW solution with pH 4
                      was achieved by using a newly purified Cyanex 301/SiO2-P
                      resin. However, the Am(III) separation was very sensitive to
                      the purity of Cyanex 301, and the improvement of its
                      stability is an important task for practical utilization.},
