Abstract
The corrosion behavior of mild steel in the presence of organic inhibitor namely 1-(8-hydroxyquinolin-2-ylmethyl)urea (HUF) has been investigated in aqueous solution containing 60 ppm of Cl - . Weight loss measurements and electrochemical impedance spectroscopy (EIS) were applied to analyze the effect of the organic compound on the corrosion inhibition of mild steel. The organic inhibitor that totally covered the mild steel surface was identified, exhibiting strong corrosion inhibition. Fluorescence spectral analysis was used to detect the presence of iron-inhibitor complex. The surface morphology has been analyzed by FTIR, UV-Visible spectroscopy, Scanning Electron Microscope (SEM) and EDAX. The inhibitor 1-(8-hydroxyquinolin-2-ylmethyl)urea has the ability to prevent the growth of certain microorganisms.
