Methods are presented by which trace amounts of several actinide elements are separated. Use is made of the large differences in distribution coefficients, so careful chromatographic techniques are not necessary. Small columns are used, allowing the desired constituent to be obtained in 10 ml or less. One method is used to separate americium, plutonium, and neptunium. These elements are sequentially eluted from columns of Dowex 1 resin in that order by 8 M HNO/sub 3/, 0.02 M ferrous sulfamate in 4.5 M HNO/sub 3/, and 0.001 M ceric sulfate in 0.25 M HNO/sub 3/. Another method is used to separate americium, thorium, plutonium, and neptunium sequentially in that order by S M HNO/sub 3/, 12 M HCl, 12 M HCL--0.1 M NH/sub 4/I, and 4 M HCL by elutriation. Protactinium and uranium follow the americium in both methods. The methods presented are characterized by a low degree of cross contsmnination. Yields are greater than 95 percent. (auth)
