Abstract The adsorption tendency of choline based ionic liquids namely, 2-hydroxyethyl-trimethyl-ammonium chloride [Chl][Cl], 2-hydroxyethyl-trimethyl-ammonium iodide [Chl][l] and 2-hydroxyethyl-trimethyl-ammonium acetate [Chl][Ac] on mild steel surface in 1 M HCl has been demonstrated using experimental and theoretical approaches. Weight loss analysis showed that inhibition efficiencies of [Chl][Cl], [Chl][I] and [Chl][Ac] increases with their concentrations. The maximum efficiencies of are in the order; [Chl][Cl] (92.04%)
