Anion-exchange separation techniques with methanol-water solutions of hydrochloric and nitric acids.
Mixed methanol-water systems were shown to be of use in the analysis of samples containing 500-mg amounts of metallic impurities for rare earths and actinides. Detailed study of the hydrochloric acid-methanol system led to improved separation of einsteinium and californium from americium and curium as well as to lanthanideactinide separations. Comparisons of elution orders are also drawn between these systems and the corresponding lithium salt systems, with emphasis on ion-hydration theories.
