A comparative study on the inhibitive effect of para-substituted anilines on corrosion of iron in 1M HCI solutions

Corrosion inhibition of Iron in 1M Hcl by some p-substituted anilines of various concentrations was studied using electrochemical measurements such as Impedance and Polarization methods. The inhibition efficiencies of the inhibitors have been found to be dependant on the nature of substituent group present at para position. It has been observed that anilines with electron donating groups increase inhibition efficiency.
