                      for the selective separation of Am(III) from an acidic
                      solution containing the trivalent actinides Am(III).
                      Cm(III), and Cf(III) as well as lanthanides. A mixture of
                      0.4 mol/L bis(chlorophenyl)dithiophosphinic acid and 0.15
                      mol/L tris(2-ethylhexyl)phosphate dissolved in $20\%$
                      $isooctane/80\%$ tert-butyl benzene was used as the
                      extractant. The process was carried out in centrifugal
                      contactors using an optimized flowsheet involving 7 stages
                      for extraction, 9 stages for scrubbing and 8 stages for
                      back-extraction. Very encouraging results were obtained. A
                      high feed decontamination factor was obtained for Am(III) (>
                      1000), and recovery in the product after stripping was
                      higher than $99.8\%.$ The Am(III) product was contaminated
                      with $0.47\%$ Cm(III). More than $99.9\%$ Cf(III), Eu(III)
                      and > $99.5\%$ Cm(III) inventories were directed to the
                      raffinate and the contamination with Am(III) (< $0.08\%)$
                      was low. The experimental results were in good agreement
                      with the predictions of a computer code.},
