Abstract
The inhibitive effects of acid extracts of Zea mays cobs on the corrosion of mild steel in 1M H2SO4 solution were
investigated using spectrophotometric method for determination of phytochemicals, Infrared Measurement (FTIR)
to determine the compound contained, Atomic absorption spectrometry (AAS) to study dissolution rate and
scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) to study the surface
morphology of mild steel before immersion in acid, after immersion without the presence of inhibitor and after
immersion in the presence of inhibitor. Result of the research shows positive indication that Zea mays cobs contains
phytochemical that can inhibits corrosion caused by the acid. The FT-IR studies revealed the presence of functional
groups such as -NH2, ROR, -C=C-, -COOH, -C=O, and -CONH2 in the extract. The SEM-EDX and AAS result
confirms that the extract reduced the corrosion rate of mild steel, hence, reduced the dissolution rate of the iron
