Abstract

The synergistic inhibition of corrosion of mild steel in 0.5 M H2SO4 by a combination of cyclohexylamine (CHA) and iodide ions has been studied using different electrochemical techniques. Corrosion inhibition is found to decrease with increase in the concentration of CHA. Iodide ions are found to enhance the inhibition by CHA considerably. Synergistic parameters such as S1 and S0 obtained from values of inhibition efficiency and surface coverage are found to be more than unity. This observation clearly shows the synergistic influence of iodide ions on the corrosion inhibition by CHA. The absorption of CHA alone and in combination with iodide ions obeys Langmuir’s absorption isotherm
