This investigation demonstrates corrosion inhibition in mild steel using Dioscorea alata leaf extract, suggesting its application in oil and gas pipelines.
Key Points
The extract achieved maximum corrosion inhibition efficiency of 83.3% within the first five days.
Weight loss measurements indicated effectiveness decreased over time, with ΔG°ads values between -9.5491 and -9.7165 kJ mol-1.
Phytochemical screening revealed that saponins, terpenes, and steroids are present in the leaf extract.
Results from potentiodynamic tests showed maximum inhibition efficiencies reaching 98.17% for certain extract concentrations.
