Adsorption and Inhibition Performance of Arachis hypogaea Extracts on 316L Steel in H₂SO₄ Solution

Article Preview

Abstract:

The inhibitive properties of Arachis hypogaea (AH) on 316L steel in 5 M H2SO4 solution was analysed with weight loss method. The results obtained reveal the inhibitive nature of AH protection with optimum inhibition efficiency of 82.58%, after 504 h. The adsorption behaviour shows the performance of AH is due to the active bonds and functional groups. The regression values obtained was close to unity at 0.9656, obeying Langmuir adsorption isotherm. It also confirms the strong adsorption nature of organic inhibitor compounds as discussed in this research by showing excellent performance of inhibition efficiencies.
