Abstract
About this talk
The potential of acarbose as corrosion inhibitor of aluminium in 0.5 M HCl was studied in various concentrations and temperatures (25–550C) by utilizing weight loss estimations, Potentiodynamic polarization techniques, Electrochemical impedance spectroscopy (EIS), Monte Carlo simulation studies, Quantum chemical computations and AFM study. The overall outcomes indicate that acarbose exhibits its highest efficiency of 94% at 4000 ppm acting as efficient inhibitor to retard aluminium corrosion in 0.5 M HCl solution. The topographical and morphological analysis of corrosion inhibition on aluminium surface was observed by AFM study which revealed the formation of thin film on the aluminium surface by acarbose. A quantum chemical calculation with DFT-theory was also done to substantiate the mechanism of inhibition. The values of the several adsorption energies derived from Monte Carlo simulations also correlates the experimental inhibition efficiency.
