Abstract

A novel extraction chromatographic material, comprised of a solution of a lead-selective macrocyclic polyether (di-t-butylcyclohexano-18-crown-6) in isodecanol sorbed on an inert polymeric support, is shown to provide a rapid and simple means for the separation of lead-210 from its daughter products for subsequent radiochemical experimentation.
