The authors study the distribution of curium, americium, and certain rare-earth elements (REE) between aqueous nitric acid solutions and FOR-tveks under static and dynamic conditions. It is shown that on introducing diethylenetriaminepentaacetic acid into the aqueous solution separation coefficients for the transplutonium elements and REE can be obtained which are sufficiently high for practical use. A method is proposed for the group separation of REE and transplutonium elements under dynamic conditions. On a column 22 cm high coefficients of approximately 500 are obtained for the purification of curium from cerium, more than 260 from neodymium, 250 from lanthanum, and 14 from europium and gadolinium. The possibility has been studied of separating palladium from transplutonium elements and REE and isolating it as an individual product.
