Abstract

There is an increase in demand for environmentally friendly and cost-effective corrosion inhibitor materials, notably in the development of corrosion inhibitors produced from natural resources. However, the composition of natural inhibitors appropriate for effective control of corrosion has yet to be extensively studied. This work attempts to synthesize and characterize an environmentally friendly corrosion inhibitor from groundnut shell powder (GSP) and coconut husk ash (CHA) and examines the inhibitory potential of GSP-CHA on mild steel under 1M HCl environment, using SEM-EDX. It was observed that the CHA-GSP contains an appropriate amount of polyphenolic, carbon and active silica components present in its constituents. These active ingredients could make the GSP-CHA blend a good candidate for a corrosion inhibitive material.
