Potentialities of a version of the radiotracer ‘foil’ (Joliot) method for sorption studies based on the measurements of X-radiation

The radiochemical basis of the application of low energy X-radiation emitting tracers for adsorption studies by the in situ radiotracer ‘foil’ method are analyzed. The optimal X-radiation energy, the effect of higher energy γ-radiation and the influence of solution thickness on the energy spectra are discussed. Some illustrative results on 57Co labelled cobalt accumulation on goldare presented as a proof the applicability of the technique.
