A process for separating transcurium elements from americium and curium, which consists of preferential solvent extraction of the transcurium elements with 2-ethylhexylphenylphosphonic acid from dilute HCl solutions, was developed and tested on a laboratory scale. Single-stage separation factors of 100 were found between californium and curium. Extraction positions of Am, Cm, Bk, Cf, Es, and Fm were determined. Extraction varied with the inverse third power of the acid composition in the range 1-4 N and directly with the third power of the extractant concentration. (auth)
