Description
Summary:The inhibition performance of penicillin G(I), methicillin(II) and nafcillin(III) on the corrosion of aluminum in a 1 M HCl solution has been tested by weight loss, Tafel polarization, scanning electron microscopy (SEM), UV-vis spectrophotometry, molecular dynamics method and quantum chemical calculations. Polarization curves indicate that the studied (I), (III) and (II) act as mixed-type inhibitors. Experimental results show that the inhibition efficiencies follow the order: nafcillin > methicillin > penicillin G. The values of inhibition efficiency and surface coverage were found to follow the order: blank < (I) (I). The results obtained from the experimental and theoretical approaches are in a reasonable agreement.
