Abstract :The investigation of the anodic oxidation of propanol at platinized platinum in 1 N H2SO4 solution by cyclic linear sweep gives the following results: In the cathodic sweep an anodic peak related to the formation of adsorbed intermediate oxidation product of propanol is observed. This adsorbed intermediate inhibites the adsorption of hydrogen. The saturation coverage of hydrogen at platinized platinum electrode in 1 N H2SO4 containing 3.10~4 M to 3.10“2M. pro¬panol is equal to 0.4. Adsorbed product is oxidized at 0.35 V. The second oxidation of propanol occurs at 0.45 V. The anodic reaction order of prop anol is equal to 0.5. The kinetic of oxidation mechanism is explained with the aid of Langmuir isoterm for dissosiative adsorption. Propanol oxidation also occurs at the Pt-0 formation region. Adsorbed intermediate is the poisoning specie for propanol oxidation.
