Study of Inhibitive Property of Pipotiazine Drug for Mild Steel in Acidic Medium

The corrosion inhibitory activity of the Pipotiazine drug molecule was studied on mild steel in 1M HCl with variety of research approaches as weight loss and electrochemical analysis including potentiodynamic polarization and electrochemical impedance spectroscopy techniques. Drug molecule successfully inhibit the corrosion of metallic sample. Results revealed the increased inhibition efficiency with increased concentration of Pipotiazine and at a concentration of 1000 ppm, the maximum inhibition efficiency was reached at 73% and inhibitor showed a mixed type of behavior. Protection of metallic sample was further validated with the scanning electron microscopy. Surface study also confirmed the reduction in roughness, on the addition of Pipotiazine drug molecule. © 2023 American Institute of Physics Inc.. All rights reserved.
