Open circuit potential/time decay characteristics of pre-anodized platinum-black electrodes were studied in the presence of methanol, formaldehyde and formic acid in 5 N H,SO,. An electrode covered with a layer of chemisorbed oxygen is passive towards electro-oxidation processes. On open circuit the

โฆ Synopsis
The anodic oxidation of methanol in a rotating tripolar wiper blade cell has been studied to determine experimental conditions required for continuous reactivation of theelectrode surface. A plausible mechanism of the reactivated oxidation reaction is also presented.

The limiting currents observed by Pavela for the anodic oxidation of methanol on platinixed platinum electrodes have been further interpreted. In alkaline electrolytes the limiting currents depend on the concentrations of methanol and sodium hydroxide and are caused by alow diffusion of either meth

While only one oxidation wave is obtained in the case of ortho and meta isomers, two distinct oxidation waves are obtained in the case of the para-isomer, the total limiting cur
