Abstract

The inhibitory effect of 1,1'-(pyridine-2,6-dihylbis(methylene))bis(5-methyl-1-H-pyrazole-3-carboxylic acid) (EM1) was estimated on the corrosion of mild steel in 1 M hydrochloric acid using weight loss, Electrochemical Impedance Spectroscopy (EIS) and Tafel polarization curves. Inhibition was found to increase with increasing concentration of inhibitor studied. The adsorption of inhibitor molecules on mild steel surface was found to be spontaneous and obeyed the Langmuir adsorption isotherm. Values of inhibition efficiency calculated from weight loss, Tafel polarization curves, and EIS are in good agreement. Polarization curves showed that EM1 behaves as mixed type inhibitor in 1 M HCl medium. The results obtained showed that EM1 could serve as an effective inhibitor of the corrosion of mild steel in hydrochloric acid solution.
