The radiochemical separation of no-carrier-added (NCA)47Sc fromnatTi targets has been studied. Scandium-47, a medium-energy β-emitter, is intended for use with labelled tumor associated monoclonal antibodies for radiotherapy. Several radiochemical methods for the separation of NCA47Sc from macroquantities of titanium and other impurities were tested. Four different procedures based on ion exchange, solvent extraction and extraction chromatography are reported. For each method, parameters such as the distribution coefficient, kinetics and recoveries are reported. The selective separation can be performed rapidly by all methods. © 1992 Akadémiai Kiadó.
