Abstract

The inhibitive properties of expired non-toxic drug of ciprofloxacin (eye/ear drops) on the corrosion of mild steel strip in 1 M hydrochloric acid medium was investigated using weight loss and electrochemical (impedance) methods. The study revealed that the inhibition efficiency increases with increases in concentration of the inhibitor, immersion period (time) and temperature. Effect of temperature was investigated at temperature range (303-343 K). This inhibitor obeys Langmuir adsorption isotherm. The inhibition activity is due to the adsorption of pharmaceutically active components which are found in the inhibitor ciprofloxacin (eye/ear drops).
