Abstract

Corrosion of metals has become a critical environmental challenge which has gained more attention over the years especially in oil and gas industries. The use of plants or organic extracts as corrosion inhibitor has become imperative as a result of their environmental acceptability, local availability as well as being renewable sources for a wide range of green inhibitors. The use of natural or organic products such as leaves and seed extracts has been widely reported but a few works have been done on the use of orange fruit seed extract as an eco-friendly corrosion inhibitor for Aluminum. Hence, in this study, the inhibiting effect of Orange fruit (Citrus synensis) seed extract on Aluminum corrosion in 1M Hydrochloric (HCL) Acid solution was investigated using weight loss measurement and phytochemical analysis. The study was conducted at a temperature of 30oC with concentration of inhibitor varied from 0-0.3g/l in the acidic medium for 10 days. It was observed that the corrosion rate increases as the concentration of the inhibitor decreases with time. The result showed that at the inhibition concentration of respectively, thereby giving the highest inhibition effect. Thus, it can be concluded that orange seed extract is a good corrosion inhibitor.
