The aim of this research is to produce an efficient corrosion inhibitor from varying concentrations of the extract of Banana peel. The research was conducted in the Department of Mechanical Engineering, College of Engineering, Covenant University, Ota, Nigeria between January and September 2021. Mild steel and Aluminium metal samples were cut into equal rectangular dimensions of 1cm by 1.5cm each summing a total of 12 samples, 6 samples of aluminium and 6 samples of mild steel. These samples were each inserted in a sulphuric acid-water mixture (acid-environment) with varying concentrations of 0 (control), 2ml, 4ml, 6ml, 8ml and 10ml of the inhibitor.The samples were weighed for weight loss every 24 hours for a time duration of 21 days. The results showed that Banana peel extract is an effective corrosion inhibitor of mild steel and aluminium in H2SO4. The corrosion rate was observed to decrease with an increase in the concentration of the inhibitor. However little research has been done on aluminium using green/organic inhibitors, hence a gap which needs to be bridged. The result from the experiment showed that the inhibitor performed better in the inhibition of aluminium than on mild steel yielding an inhibition efficiency of 67.32%relative to mild steel of 62.40%. The result showed Banana Peel Extract(BPE) can be used as a corrosion inhibitor as this will curtail the relative use of inorganic inhibitors that are harmful and toxic to the environment. Using Banana peel extract was economically good as Banana is readily available and its extract is cheap to produce.
