The aim of this research is to use the wet loss method to determine how well Moringa oleifera in H2SO4 inhibits aluminum corrosion. Weight loss was measured before and after corrosion on aluminum coupons with a thickness of 0.15cm, a width of 3cm, and a length of 4cm, all of which were 98 percent pure. Increases in inhibitor concentrations improve inhibition effectiveness, which ranges from 35.29 % to 47.06 % to 64.71 percent to a maximum of 82.35 %, but decreases as temperature and immersion time rise. The inhibition efficiency of the formulation consisting of 1M H2SO4 medium and 0.4g/L inhibition is 82.35 %. This means that the inhibitor is well-adsorbed on the surface of the aluminum metal, resulting in a significant reduction in corrosion rate. As a result, further research into corrosion inhibition should be done with this type of plant. The Langmuir adsorption isotherm (where Gads(kj/mol) is found to be -13.694 and Kads is 13.53) was followed in the adsorption of inhibitor molecules on Aluminum sheet surface. The absorption peaks corresponding to the functional groups – C=O, -C=N, C-OH, and C=C were found in the infrared spectrograph of the leaf extracts. These functional groups may have interacted with the aluminum sheet's surface, preventing oxidation. Organic compounds in the leaf extracts, such as alkaloids, saponins, tannins, and phenolics, were thought to be the source of these functional classes. Green extracts of M. oleifera are recommended for use as corrosion inhibitors against other inorganic compounds. It has a higher inhibitory performance, is readily available, biodegradable, less expensive, and environmentally friendly.
