    Inhibition of the corrosion of mild steel in H2SO4 by 5- amino-1-cyclopropyl-7-[(3R, 5S) 3, 5-dimethylpiperazin- 1-YL] -6, 8-difluoro-4-oxo-uinoline-3-carboxylic acid (ACPDQC)

    Adsorption and inhibitive efficiencies of ACPDQC on mild steel corrosion have been studied using gasometric and thermometric techniques. ACPDQC is found to be a good inhibitor for the corrosion of mild steel in H2SO4 solution. The inhibition efficiencies of ACPDQC were found to decrease with increase in temperature but increased with increase in the concentration of the extract. Thermodynamic/adsorption considerations revealed that the adsorption of ACPDQC on the surface of mild steel is exothermic, spontaneous and proceeded via the mechanism of physical adsorption. Classical adsorption isotherms of Langmuir and Frumkin best described the adsorption characteristics of ACPDQC on the surface of mild steel.
