Аннотация
The corrosion inhibition effect of Origanum Vulgare (oregano) on aluminium in acidic medium was examined. The techniques involved weight loss method, quantum chemical analysis and SEM. It was seen that inhibition efficiency of oregano varied directly with concentration of inhibitor and inversely with temperature. A maximum inhibition efficiency of 97.7% was seen at 4000 ppm of inhibitor. The process of adsorption was seen to follow Langmuir adsorption isotherm. Quantum chemical studies were used in determining the molecular structure and to elucidate the electronic structure and reactivity of inhibitor.
