Abstract The influence of dimethyl sulphoxide on hydrogen permeation and corrosion inhibition of mild steel in 1 N HCl and 1 N H2SO4 has been studied using weight loss measurements, gasometric studies, galvanostatic polarisation studies and hydrogen permeation measurements. The performance of this compound as an inhibitor of corrosion is not very much encouraging. It is found to perform as a mixed type corrosion inhibitor but predominantly as a cathodic inhibitor in both the acids. The adsorption of this compound on mercury from both the acids is studied using capillary electrometer. Dimethyl sulphoxide is found to bring down the extent of hydrogen permeation through mild steel in both the acids. The adsorption of the compound from the acids is found to obey Temkin's adsorption isotherm
