Preparation of carrier-free radionuclides from cyclotron targets by continuous electrophoresis, I

Abstract

Continuous electrophoretic separation of the components of the manganese, iron, copper and silver cyclotron targets bombarded with deuterons is described. The rates of separation were: managanese target, 4.4 mg Mn/hr; iron target, 1.5 mg Fe/hr; copper target, 1.7 mg Cu/hr; and silver target, 6.7 mg Ag/hr. The radionuclides were separated in carrier-free form and were of high radiochemical purity. The results are represented by radioautographs of the continuous electrophoretic processes, and by diagrams showing the distribution of the target material and of radioactivity along the collecting glasses. The radiochemical purity of the separated radionuclides was checked by the gamma spectra, by estimation of the beta-energies, and by evaluation of the decay curves.
