Adsorption and corrosion inhibition characteristics of some organic molecules containing methoxy phenyl moiety on mild steel in hydrochloric acid solution
The influence of three newly synthesized molecules on the corrosion inhibition of mild steel in acid media is studied. From Tafel slopes, it is evident that the anodic reaction is more polarized. Impedance study reveals that the increase in Rct values can be attributed to the formation of a protective film and the decrease in Cdl values is due to an increase in the thickness of the electrical double layer. Total energy, EHOMO and softness are in the order of 3-MPTT > 4-AMTT > 3-MAH and dipole moment, ELUMO, energy gap, ionization potential and hardness are in the order of 3-MPTT < 4-AMTT < 3-MAH.
