A brief survey is given on the present state of the tracer adsorption studies. The main trends in the investigations are illustrated through examples taken from the results reported in the seventies. The following main topics are considered: 1. Developments in the improvement of the experimental technique. Different versions of experimental apparatus are presented discussing briefly the drawbacks and advantages of the methods used. 2. Ion adsorption studies. Examples for the application of the tracer method to the study of simultaneous adsorption processes are presented. 3. Adsorption of organic species. Problems connected with the equilibrium properties and the interpretation of the experimental results are summarized. Efforts made for the determination of the nature of simple chemisorbed species are reviewed. 4. Coupling of polarization and tracer adsorption studies. The possibility of simultaneous measurement of adsorption and reaction rate in the course of electrocatalytic processes is discussed. The illustrative examples refer mostly to platinum electrodes. Results obtained in the case of other electrodes are cited.
