A new approach for the study of ion transport by an in situ radiotracer method is presented. The method is based upon the measurement of the intensity and energy spectrum change of -radiation during the penetration of labeled species. The applicability of the radiotracer technique is detailed through the measurement of the transport of labeled chloride ions into a PERMAPLEX-A20 anion exchanger membrane. The proposed method is applicable to in situ monitoring of the motion of ions in the membrane (or adsorbent).
