1-Butyl-3-methylimidazolium methane sulfonate ionic liquid corrosion inhibitor for mild steel alloy: Experimental, optimization and theoretical studies.

The current research reports the performance of 1-butyl-3-methylimidazolium methane sulfonate ([CMIM][OMs](IL)) as effective corrosion inhibitor for mild steel in 1 M HSO electrolyte. For proper evaluation, weight loss, electrochemical study, theoretical modeling and optimization techniques were used. Weight loss and electrochemical methods shows that the inhibition performance of [CMIM][OMs] on the metal surface strengthens as the concentration increases.
