Laboratory Experiments
An Improved Method for the Separation of Lead-210 from Ra-DEF for Radioactive Equilibrium Experiments: Microscale Liquid-Liquid Extraction Using a Polymer-Supported Crown Ether

Vol. 73 No. 2
p. 182
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.
