Abstract

It has been shown that, when there is o-fluorophenylbiguanidine (o-FPBG) and its concentration increases (from 0.5 to 40 mM), the change of the nature of slow step of hydrogen evolution on iron is observed in the following order: slow discharge → limiting chemical recombination → slow lateral diffusion → limiting discharge. This series is in sufficient correlation with the experimental adsorption isotherm of o-FPBG on iron.
