Abstract

The inhibitive performance of Sapindus on the acidic corrosion of Aluminium was studied using myriad experimental and computational techniques. Sapindus showed 98% of inhibition efficiency at 2000 ppm. Inhibition efficiency of Sapindus was found to be directly proportional to its concentration in the acidic medium. Effect of temperature was also studied and it played a corrosive role by increasing the corrosion rate and decreasing the inhibition efficiency of Sapindus. Thermodynamic parameters of adsorption were derived to enunciate the findings. Mechanism of adsorption was also explored using electrochemical impedance spectroscopy and potentiodynamic polarization (Tafel) studies which displayed a profound physisorption mechanism.
