Green corrosion inhibitor from seed extract of Areca catechu for mild steel in hydrochloric acid medium
Source abstract
Abstract
The adsorption and corrosion inhibition effect of acid extract of the seeds of Areca catechu on mild steel in hydrochloric acid medium were analyzed. Inhibition efficiency and thermodynamic parameters such as energy of activation for corrosion reaction of mild steel (E), heat of adsorption of the inhibitor on the metal surface (Q), change in entropy (∆S), and change in free energy (∆G) were obtained using weight-loss data. The nature of adsorption of the inhibitor on the metal surface was verified by plotting Temkin’s adsorption isotherm. Electrochemical parameters were obtained by AC impedance and Tafel polarization studies. Infrared (IR) spectra and scanning electron microscope techniques were also employed to examine the mechanism of corrosion inhibition property. All the results obtained were encouraging and hence bring to light a new alternate, eco-friendly material for the corrosion inhibition of mild steel in acid medium.
