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 𝐦𝐠
𝐋 while for Musa
paradisiaca DNA, the highest corrosion inhibition was 55.0720% at the
conditions, 10˚C and 20 𝐦𝐠 𝐋 and for the hybrid, the highest corrosion
inhibition efficiency was 60.8697% at the conditions, 10˚C and 20 mg ⁄ L.
