Corrosion Inhibition of Carbon Steel by Schiff Base Compounds
Abstract:
Inhibitory effects of two Schiff bases N,N'-bis(salicylidene)-1,2-ethylendiamine(SB-Ⅰ) and salcylidene-pyridine-2-yl-amine(SB-Ⅱ) on the corrosion of carbon steel in 1 mol/L HCl solution were studied via mass loss measurement method,polarization and electrochemical impedance spectroscopy.The results show that compounds SB-Ⅰ and SB-Ⅱ have fairly good inhibiting properties for carbon steel corrosion in hydrochloric acid with the best efficiencies of 85% and 92%,respectively,at 20 mmol/L additive concentration,and they belong to anodic inhibitors.
