mild steel - Opis:
- The potential of flavonoid extract of Erigeron floribundus as green inhibitor for the corrosion of mild steel in 2 M HCl solution was studied using gasometric method. The results obtained, indicated that the extract is an adsorption inhibitor for the corrosion of mild steel. The inhibition efficiency of the inhibitor was found to increased with increase in concentration of the inhibitor. From the observed trend for the variation of inhibition efficiency with temperature and the range of value obtained from activation energy (16.16-3.02 KJmol-1), enthalpy (13.5-38.84 KJmol-1), entropy (-22.67 to 88.44 KJmol-1) and free energy (-4.23 to -2.61 KJmol-1), a chemical and physical adsorption mechanism is propose for the adsorption of the inhibitor on the mild steel surface. In addition, the adsorption is endothermic, spontaneous and is best described by Langmuir adsorption isotherm.
