The method of separation of californium, einsteinium, fermium, and certain lanthanides, based on the use of ammonium ..cap alpha..-hydroxyisobutyrate as the eluent, has been improved. The use of a 0.10-0.14 M solution of this reagent and columns (9 x 0.5 cm) filled with the resin Aminex SB with particle size 20-25 ..mu.., permitted the production of about 0.5 ..mu..g of einsteinium-253 from irradiated californium-252 with coefficient of purification of einsteinium from californium in two cycles of adsorption and elution of approx. 10/sup 10/. The coefficient of separation of californium and einsteinium is equal to 1.6 and that of einsteinium and fermium 1.9. The behavior of certain lanthanides in the separation of californium, einsteinium, and fermium using a 0.010 M solution of ammonium ..cap alpha..-hydroxyisobutyrate is discussed.
