Abstract: (237 Views)
In this research, the corrosion inhibition of Citrus Aurantium peel extract as a green and environmentally friendly
inhibitor on the corrosion of mild steel in 1 M sulfuric acid media has been investigated. The studies were
evaluated using weight loss (WL), electrochemical impedance (EIS) and potentiodynamic polarization (PDP)
methods. And all the tests were in good agreement and showed that the efficiency increases with increasing
concentration of inhibitor. EIS showed that the Citrus Aurantium peel extract formed a protective layer on the
metal surface and a yield of 98% was achieved using 1500 mg / L inhibitor. Polarization curves showed that the
inhibitor affects both anodic and cathodic reactions and inhibitor is a mixed inhibitor. Thermodynamic and
adsorption studies showed that the inhibitor adsorption on the surface follows the Langmuir adsorption isotherm
model and the adsorption is spontaneous both physically and chemically. Also, the chemical properties of green
inhibitor were investigated by FTIR, which shows the presence of O and N and aromatic groups in Citrus
Aurantium peel as effective factors in corrosion inhibition.
