عنوان انگلیسی The Effect of Alyssum Floribundum Boiss. & Balansa (Brassicaceae) Leaves Extract on the Corrosion of Mild Steel in an Acidic Medium
چکیده انگلیسی مقاله In this study, the inhibition effect of Alyssum floribundum Boiss. & Balansa on the corrosion of mild steel was examined using electrochemical measurements in a 1M H2SO4 solution. The experimental results demonstrated that the extract of Alyssum floribundum exhibited significant inhibitory performance. According to the potentiodynamic polarization measurements, the highest inhibition efficiency was 98% when using a 1M H2SO4 solution containing 20 g/l of the plant extract. To determine the activation energy and temperature dependence of the corrosion inhibition process, polarization measurements were conducted at different temperatures ranging from 27°C to 60°C. The inhibition efficiency increased with an increasing concentration of the inhibitor, and the activation energies were found to be 33.56 kJ·mol-1 in a 1M H2SO4 solution and 96.98 kJ·mol-1 in the presence of the inhibitor (1M H2SO4 + 20g/ml). It was observed that the Langmuir adsorption isotherm was suitable for the adsorption of A. floribundum leaf extract on the surface of mild steel in an acidic solution.
