Efficient quaternary ammonium salt as corrosion inhibitor for steel pickling in sulphuric acid media

Abstract

A study is carried out on the resistance to corrosion of mild steel in 5 per cent H₂SO₄ solutions at temperatures between 30 and 60°C. The effectiveness of quaternary ammonium salt used as corrosion inhibitor under the same experimental conditions was also investigated. Weight loss results and electrochemical data showed the good inhibiting action of the inhibitor, acting as anodic type. Thermodynamic parameters for adsorption of the compound are calculated using the Temkin adsorption isotherm.
