Quantities of heavy element (americium and curium) up to 2.3 g have been successfully separated by chromatographic elution from cation resin using alpha-hydroxyisobutyrate in equipment originally designed for decigram-scale separations of /sup 252/Cf and heavier elements. The high-pressure ion exchange process was reliable and relatively easy to operate. Overall curium recoveries of 80 to 90% were readily achieved with decontamination from americium by factors of 400 to 500. The product and waste streams are both in forms readily coupled to further processing steps.
