In this research, nano-particles of the Barks of Vitelleria Paradoxa, Ficus Thonnigil and Hyptis Suaveolens Extract have been characterized to determine their suitability as green corrosion inhibitors for mild steel.Characterizations of the plant materials was done by qualitative and quantitative analyses, Fourier transforms infrared (FT‑ IR) spectroscopy and scanning electron microscopy attached with energy dispersive x-ray (SEM/EDX). The experimental results showed that, the phytochemical analysis revealed that,these materials have active biocomponents; glycosides, saponins, tannins, flavonoids, alkaloids, steroids and phenols that could be responsible for corrosion inhibition of mild steel. The FTIR showed that, the plant materials containfunctional groups with C-H stretch, O-H stretch, C=C stretch, S = O stretch, CO stretch, CC triple bond and C–H bend at various frequencies which shows the presence of aromatic groups that could be responsible for the inhibitive properties of these materials while the SEM/EDX showedhigh amount of oxygen 64.6 Wt% in the nano particles of Vitelleria paradoxa and 73.1 Wt% in the nano particles of Ficus Thoningii. The results of the study show that Hyptis Suaveolensis (HSLP) extract blended with nanoparticles from the back of Ficus thoningii and Vitelleria Paradoxa have the potential to be utilized as green corrosion inhibitors on mild steel and could be an alternative source of green corrosion inhibitors which could serve as an alternative to synthetic inhibitors which are expensive, cancerous and environmentally unfriendly.
