✦ Synopsis

Various methods of the tracer technique have been elaborated for investigating the adsorption of ions and organic compounds1 12. Among the methods reported in the literature, those described in refs. 4, 6 and 9 seems to be the most convenient for tracer techniques with isotopes emitting soft/?-rays. The three methods are, in fact, variations of Joliot's method further developed for different purposes. The method was originally devised for studying the deposition of metals by the tracer technique. The essential part of it is an electrolytic cell whose cathode is a smooth platinum or gold foil which serves at the same time as the "window" of the detector. The apparatus described below is used for another variation of this method. APPARATUS

In the last decade detailed mechanism-determination studies have been carried out on the oxidation of oxalic acid 1-6. A possible mechanism has been suggested by Johnson et al. in the case of platinum and gold electrodes 4'5. In the proposed mechanism the adsorption step and the adsorption equilibr
