A THEORETICAL APPROACH TO THE STUDY OF SOME PLANT EXTRACTS OF balanites aegyptiaca AS GREEN CORROSION INHIBITOR FOR ALUMINIUM ALLOY IN ACIDIC MEDIUM AUTHORS: B. El-yaqub, S. O. Okeniyi, P. E. Omale, O. O. Okeniyi ABSTRACT Abstract The plant extracts are biodegradable, eco-friendly, cheap, readily available, non-toxic and easily assessable source of material which can be used as corrosion inhibitor for Aluminium Alloy in acidic medium. The effect of the plant was investigated by theoretical method. Highest occupied molecular orbital (HOMO), lowest unoccupied molecular orbital (LUMO), dipole moment, ionization energy, electron affinity, electronegativity, chemical potential, global hardness, mulliken charges on heteroatoms were calculated and interpreted. Quantum chemical calculations revealed the adsorption of molecules onto the surface of the Alloy. Key words: Aluminium Alloy, corrosion inhibition, plant extracts, quantum chemical calculations.
