This document concerns the purification of kilocurie quantities of Promethium-147 by ion exchange. Twenty thousand curies of Pm-147 in a mixture of rare-earth fission products was processed by ion exchange on a cation resin, using ammonium citrate solution as the eluant, until the desired purity of Pm-147 was obtained. Promethium was present to the extent of about 1.6 percent in the starting mixture and was increased to 60 percent in the final product. Procedures, typical elution curves, methods of analysis, losses, material balances, and a description of the equipment were given for the process. Multikilocurie quantities can be produced with similar equipment, with little difficulty contributed by radiation or radiation damage when feed material of the appropriate concentration is available. Tables and figures are included.
