Abstract

Carbon steel enjoys wide usage across many industries and sectors due to the wide range of its mechanical characteristics and costs. However, carbon steels are highly prone to corrosion. Corrosion is an undesirable process with devastating consequences. While there are several methods of preventing corrosion, corrosion control using extracts of plant seeds, fruits, flowers, leaves, barks and roots has been attracting attentions due to environmental, cost and sustainability concerns. However, some of these plant materials particularly the seeds and fruits have great economic values due to nutritional, medical and socio-cultural usefulness. Hence the need to use extracts from their wastes (peels and pods). In this study the use alligator pepper pods and mango peels extracts as anti-corrosion agents on carbon steel in acidic environment were analysed and compared. Results showed that the alligator pepper pod and mango peel extracts contained phytochemicals capable of inhibiting corrosion. The mango peels contained higher contents of alkaloids, flavonoids, saponins, and terperniods compared to alligator pepper pod extracts. The glycosides, phenols and tannins contents of alligator pepper pod extracts were slightly higher than those in mango peels extracts. Results of the corrosion tests showed that carbon steel is prone to corrosion in acidic medium. Further outcome of the study also showed that both extracts are efficient in inhibiting carbon steel corrosion in HCl solution. The corrosion prevention efficiency of alligator pepper pods and mango peels extracts are comparable, but that of mango peels is slightly better. Results of this study showed that corrosion inhibition efficiency of the extracts decreases with time but increases with concentration.
