Jennewein, A. Schmidt, A. F. Novgorodov, Syed M. Qaim, Frank Rösch] Arsenic-72 is a positron emitting isotope with promising properties for syntheses of 72As-labelled radiopharmaceuticals for future application in positron emission tomography. This work describes the radiochemical separation of no-carrier-added 72Se from cyclotron irradiated germanium targets and the development of a 72Se/72As radionuclide generator, avoiding the addition of any selenium carrier. Using a vertical quartz tube device, no-carrier-added 72As is nearly quantitatively released from various chloride salt solutions containing 72Se within 10min at a temperature of 100°C in an HCl gas flow. The kinetics of the 72Se/72As isotope generator has been studied in relation to temperature, salt charge, and redox-stability. Under optimised conditions, 72Se remains almost quantitatively (>99.7%) in solution. © 2004 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Jennewein M. aut Schmidt A. aut Novgorodov A.
