Hexadecyl trimethyl ammonium bromide as an effective inhibitor for the corrosion of steel in sulphuric acid solution

Abstract

The corrosion of steel in sulphuric acid containing hexadecyl trimethyl ammonium bromide (HTABr) was studied over the temperature range 30‐60°C at different inhibitor concentrations of 0.5 × 10^‐3 to 2.5 × 10^‐3 M/L by the mass‐loss method. Langmuir’s adsorption isotherm fits the experimental data for the studied compound. Thermodynamic parameters for dissolution and adsorption were calculated. It is observed that HTABr can be used as an effective inhibitor.
