Abstract
Three different floxacins (Ciprofloxacin, Levofloxacin, and Norfloxacin) were used to enhance the inhibition property of Dextrin (Dex) against the dissolution of mild steel in acid medium. Substantial increase in the inhibition property was observed against mild steel dissolution by the addition of floxacins than with pure Dex. Weights loss experiments proved the potential of Fluoroquinolones (FQs) in enhaning the corrosion inhibition property of Dex on metal by proving its best ability at lower concentrations. Adsorption of Dex and floxacins on metal surface was observed to accept with Langmuir adsorption isotherm. The results from EIS studies add to the enhancing property of floxacins on Dex. While the mixed type behavior of inhibitors were confirmed by polarization studies, images from SEM, EDS and AFM gathers strength to propose the formation of protective layer.
