Sažetak

The significant anticorrosive property of the antibiotic drug doxycycline hydrochloride (DCH) was investigated by electrochemical techniques such as potentiodynamic polarization, electrochemical impedance and chronoamperometric techniques. DCH inhibited the pitting corrosion of aluminium alloy 6061 (AA6061) in 3.5% NaCl media with 90% efficiency. The adsorption of DCH on AA6061 conform Langmuir isotherm by means of physisorption. Quantum chemical calculations were evaluated to ascertain the active sites of DCH molecule responsible for adsorption and to support the experimental findings.
