Abstract :
The inhibition performances of nafcillin (III), methicillin (II) and penicillin G (I) on the corrosion of copper
in HCl was studied and tested by weight loss, Tafel polarization, SEM, UV-vis spectrophotometry, molecular dynamics
method and quantum chemical calculations. Polarization curves indicated that the studied inhibitors act as mixed-type
inhibitors. The values of inhibition efficiency and surface coverage were found to follow the order: Blank
methicillin (II)> penicillin G (I), which confirmed that nafcillin has the strongest interaction with the metal surface.
The obtained results from experimental and theoretical methods were in reasonable agreement.
