COMPARISON OF CORROSION INHIBITION POTENTIALS OF PERSEA AMERICANA SEED EXTRACTS IN TWO DIFFERENT CORRODENT MEDIA

ABSTRACT Corrosion is a persistent and costly problem in industrial and environmental systems where metals interact with aggressive chemical media. The search for environmentally friendly corrosion inhibitors has led researchers toward plant-based materials that contain naturally occurring organic compounds capable of forming protective films on metal surfaces. This research investigates the corrosion inhibition potentials of Persea americana (avocado) seed extracts in two different corrosive media. The study aims to determine the effectiveness of the seed extract as a corrosion inhibitor and to compare its inhibition efficiency in two corrosive environments. Mild steel samples were exposed to the corrosive media in the presence and absence of the plant extract. Weight loss measurements were used to evaluate corrosion rates and inhibition efficiencies. The results revealed that the Persea americana seed extract demonstrated significant corrosion inhibition properties. The efficiency of inhibition increased with higher concentrations of the extract. However, variations were observed between the two corrosive media, indicating that environmental conditions influence inhibitor performance. The findings suggest that Persea americana seed extract possesses promising corrosion inhibition properties and could serve as an environmentally friendly alternative to synthetic corrosion inhibitors. The study contributes to the growing body of research on green corrosion inhibitors and highlights the potential of agricultural waste materials in industrial corrosion control.
