Overview

Observational analysis shows 79.77% weight loss in mild steel, indicating Solanum Torvum as an effective corrosion inhibitor.

Key Points

  • Corrosion rate decreased significantly to 44.08 mmpy at 303 K, demonstrating the protective action of Solanum Torvum extract.
  • Thermodynamic analysis revealed activation energies between 64–68 kJ/mol, indicating effective spontaneous adsorption properties.
  • Electrochemical studies showed a reduction in corrosion current density from 4565 to 907 µA/cm², highlighting the efficiency of the extract.
  • Formation of a protective inhibitor film was confirmed via SEM, UV, FTIR, and EDX, supporting its effectiveness in acidic environments.
