Abstract:	Zinc and nickel hexacyanoferrates (II) present a high affinity for²²³Fr and no retention for²²³Ra in hydrochloric acid solutions with concentrations greater than 0.5N. Hydrated antimony pentoxide is the best sorbent for²²³Ra. Incorporated in a composite exchanger, it could be used for decontamination purposes.
