Radiochemical studies on the ion exchange behaviour of some radionuclides

Ion exchange systems found wide application in radiochemical separation of many radiotracers. In nuclear technology, ion exchange resins are usually used for purification of many of the fission products radio-nuclides as well as actinides and lanthanides . To achieve a good separation conditions, selectivity of the ion exchange system for the ion to be isolated is required. one approach to improve such selectivity is to manipulate the ionic form of the elements to be separated. This modification can be reached by the presence of certain complexing ligands. In this concern, the cation exchange behaviour of many metal ions was investigated in the presence of negatively charged ligands. On the other hand, the effect of neutral ligands on the ion exchange processes with organic resins has, so far, received little attention. Therefore, it was found of interest to add more information on the cation exchange behaviour of some radiotracer in the system comprising , the cation exchanger dowex 50 W -X8, the neutral ligand; benzylamine and different mineral acids
