Detailed exploration of anticorrosive application of rhamnogalacturonan polysaccharide from Althaea officinalis as an eco-friendly alternative corrosion inhibitor for mild steel in 15% HCl medium

Key Points

• Rhamnogalacturonan polysaccharide significantly inhibits corrosion in mild steel when exposed to 15% HCl solution, providing a sustainable alternative.
• The corrosion rates of treated mild steel samples were markedly lower compared to untreated controls, indicating strong protective properties.
• Assessment employed standardized electrochemical techniques to evaluate the effectiveness of the polysaccharide as a corrosion inhibitor.
• These findings support the use of eco-friendly materials in industrial applications, highlighting the potential for greener corrosion prevention solutions.
