Inhibitive action of various azoles on the corrosion of mild steel in sulphuric acid. 2

Abstract

This paper presents the second part of the discussion on the results of experiments carried out to determine the inhibitive action of various azoles on the corrosion of mild steel in sulfuric acid. For all the azole compounds studied, the inhibitive efficiency increases with temperature from 30°C to 50°C. This efficiency may be due to two reasons: A higher activation energy is available for adsorption at higher temperatures; and surface coverage is enhanced at higher temperatures by the inhibitor molecules.
