Corrosion Inhibitive Action of Hesperidin methyl chalcone (HMC) on Aluminum in H2SO4

Abstract

Using both theoretical and experimental techniques, the impact of Hesperidin methyl chalcone (HMC) on Aluminum corrosion in 0.5M H2SO4 was examined at various temperatures. Measurements of weight loss revealed that the inhibitory efficiency rises with rising HMC concentrations and falls with rising temperatures. An inhibitor's overall rising inhibitory efficacy is ascribed to the bulk of the solution's adsorption onto the aluminum surfaces. The Langmuir adsorption isotherm is best fitted by the adsorption process model, as well as calculated thermodynamic parameters, were spoken about. Thermodynamic characteristics show that the HMC uses a combination of physisorption and chemisorption to adsorb spontaneously onto metal surfaces and delay corrosion. The effect of temperature on Aluminum's HMC inhibition efficiency in 0.5M H2SO4 is explained by the activation parameters. The experimental results are supported by the quantum chemical parameters, which likewise show good agreement with them.
