Corrosion inhibition potential of ethanol extract of Bryophyllum pinnatum leaves for zinc in acidic medium

Corrosion is a significant challenge in various industrial applications, particularly within oil and gas sectors, leading to financial losses estimated at over $2.5 trillion globally. This study aims to investigate the corrosion inhibition potential of ethanol extract from Bryophyllum pinnatum leaves on zinc in acidic environments. A series of electrochemical experiments were conducted to assess the effectiveness of the plant extract as a corrosion inhibitor. The methodologies involved potentiodynamic polarization and electrochemical impedance spectroscopy to evaluate inhibition efficiency and mechanism. Results indicated that the ethanol extract of Bryophyllum pinnatum significantly reduced the corrosion rate of zinc by forming a protective layer on the metal surface, effectively inhibiting electron transfer reactions. The optimum concentration for corrosion inhibition was determined, revealing that the natural extract displays both electrochemical and physical adsorption mechanisms. This study contributes valuable insights into sustainable corrosion management strategies using plant-derived materials, proposing an alternative to traditional synthetic inhibitors that may pose environmental hazards. The findings underscore the potential of Bryophyllum pinnatum as an eco-friendly corrosion inhibitor in industrial applications.
