Abstract
Corrosion inhibition of aluminium by leaf extract Telfaira occidentalis in 1.5 M HCl was investigated using the gasometric technique at 28oC. Results obtained showed that the extract displayed high inhibition efficiency against corrosion of aluminium in 1.5 M HCl solution. The extract displayed nearly the inhibition efficiencies at concentration range 10 – 50% dilution of the extract. The corrosion inhibition mechanism followed Langmuir adsorption isotherm at the studied temperature. This suggests the extract constituent chemisorbed on the aluminium surface forming a protective film minimising direct contact with the corrodent.
