An Automated Anion-Exchange Method for the Selective Sorption of five Groups of Trace Elements in Neutron-Irradiated Biological Material

摘要

An anion-exchange method based on fast selective sorption steps from mixtures of sulfuric, hydrotropic, and hydrochloric acid solutions has been developed for the separation of five different groups of radioactive trace elements in neutron-irradiated biological material. The separations are performed automatically with a simple proportioning pump apparatus. The apparatus allows the exact adjustment of influent solutions to the series of ion-exchange columns. The practical application of the method is described in detail. The successful use of the method is practically independent on the level of 24 Na activities present in the sample.
