Inhibition of Mild Steel Corrosion in 0.25 M H2SO4 Using Tetracarpidium conophorum Shell Extract

The capacity of aqueous Tetracarpidium conophorum Shell (TCE) Extract to inhibit pipeline steel corrosion in 0.25 M H2SO4 acid was investigated using weight loss and Uv-visible spectroscopy techniques. The phytochemical components of Tetracarpidium conophorum were identified using GC-MS analysis. The results obtained shows that aqueous Tetracarpidium conophorum shell extract decreased the corrosion rate, while the corrosion inhibition efficiency increased with increase in exatract concentration. The Uv-visible spectra indicated a chemical interaction between the TCE molecules and atoms of Iron on the pipeline steel surface, while GC-MS analysis showed the presence of organic compounds with hetero-atoms for adsorption on the steel surface.
