“…These features obviously can be combined within the same molecule such as Schiff bases. In the past few years, the inhibition of various metals such as iron, copper, zinc, aluminum, and carbon steel corro sion in acid solutions by Schiff bases with environ mental considerations has attracted more attention [12,13]. Schiff bases can conveniently be synthesized from relatively cheap starting materials.…”

The potential of di (Resacetophenone) 1,2 cyclohexandiimine as an environmentally friendly corrosion inhibitor for steel has been investigated in 1 M HCl using potentiodynamic polarization, electro chemical impedance spectroscopy and chronoamperometry measurements. All electrochemical measure ments suggest that this compound is an excellent corrosion inhibitor for mild steel and the inhibition effi ciency increases with the increase in inhibitor concentration. The effect of temperature on the corrosion behavior of mild steel with the addition of the Schiff base was studied in the temperature range from 25 to 65°C. Adsorption of this inhibitor follows the Langmuir adsorption isotherms. The value of Activation energy and the thermodynamic parameters such as ΔH ads , ΔS ads , ΔK ads and ΔG ads were calculated by the corrosion currents at different temperatures and using the adsorption isotherm. The morphology of mild steel surface in the absence and presence of inhibitor was examined by scanning electron microscopy (SEM) images.
