Extraction chromatography flow-sheet employing octyl(phenyl)-$$N,N$$-diisobutylcarbonoylmethylphosphine oxide (CMPO) and $$bis$$(2-ethylhexyl) hydrogen phosphate (HDEHP) extractants for trivalent minor actinide recovery was modified to improve column separation performance. Excellent trivalent minor actinides recovery performance was obtained by column separation experiments on nitric acid solution containing the trivalent minor actinides and representative fission product elements, i.e. recovery yields $$>$$ 93% with sufficient decontamination factors against the fission products. Those are the best performance which we have ever obtained by experiments inside hot cell.
