Inhibitive Effect of Imidazolium Based Aprotic Ionic Liquids on Mild Steel Corrosion in Hydrochloric Acid Medium

Year: 2011

Type: article

Abstract: The inhibition performance of imidazolium based aprotic ionic liquids (ILs) [C4mim][NO3], [C4mim][BF4] and [C4C1mim][BF4] on mild steel corrosion in hydrochloric acid was studied at 303-313K using weight loss and hydrogen evolution techniques. Inhibition efficiency increased and corrosion rate decreased with increase in ILs concentration. The order of the inhibition efficiency is [C4mim][NO3] > [C4mim][BF4] > [C4C1mim][BF4]. The adsorption of ILs follows Langmuir adsorption isotherm model. Physical adsorption is proposed from the values of ΔGads obtained.
