The study investigated green corrosion inhibitors of musa on mild steel. The ever present threat to the integrity of a metals’ structure called corrosion has led to the heavy use of preventive measures in order to slow down its’ progression. One of such preventive measures is the use of corrosion inhibitors. The use of corrosion inhibitors has proven to be very successful making their application one of the most used measures against corrosion. However, despite the successful use of corrosion inhibitors, having high corrosion inhibition efficiencies; some corrosion inhibitors have been found to be moderately to highly toxic to man and the environment. A call for alternative inhibitors to the toxic inorganic corrosion inhibitors was made and the answers arrived at by researchers, were the use of “Green Inhibitors”. This research focused on the use of DNA extracted from two varieties of plants from the Musa species and a hybrid of the two as corrosion inhibitors of mild steel with the corrosive medium being HCl. Experiments were undertaken at varying temperatures of the corrosive medium and at varying concentrations of DNA in order to determine the optimal temperatures and concentrations that give the highest corrosion inhibition efficiencies of the two Musa varieties and the hybrid. The highest corrosion inhibition for Musa acuminate DNA was 58.1818% at the conditions, 55˚C and 5 𝐦𝐠𝐋 while for Musa paradisiaca DNA, the highest corrosion inhibition was 55.0720% at the conditions, 10˚C and 20 𝐦𝐠𝐋 and for the hybrid, the highest corrosion inhibition efficiency was 60.8697% at the conditions, 10˚C and 20 mg ⁄ L.
