[Omim][Pro] Amino Acid Ionic Liquids as a Corrosion Inhibitor for Copper in 3.5 % NaCl Solution

Abstract:

The corrosion inhibition effect of the 1-alkyl-3-methylimidazolium proline ([Omi [Pro]) for copper in 3.5% NaCl solution was investigated by using electrochemical methods. The results indicated that: the inhibition efficiency of [Omi [Pro] was more than 90%, which showed the excellent corrosion inhibition performance. The inhibition efficiency increased with increasing concentration of [Omi [Pro], and decreased with increasing temperature, but it changed very little when the concentration arrived at 0.001 mol/L. [Omi [Pro] was a good mixed-type inhibitor which mainly inhibited anodic processes.
