Online published on 28 August, 2014. Abstract A theoretical study has been performed on Ciprofloxacin drug using Density functional theory (DFT) and the inhibitive effect of the drug against the corrosion of mild steel in acidic medium is elucidated. The properties most relevant to their potential action as corrosion inhibitor has been calculated: EHOMO, ELUMO, energy gap (ΔE), dipole moment (μ), Total energy (TE) and Mulliken Charges. All calculation has been performed using the GAUSSIAN 03W suite of programs. The inhibitor compound exhibited the highest inhibition efficiency.
