Abstract
Aqueous extract of wild clary has been used in place of a corrosion inhibitor in the corrosion control of carbon steel. The major components of this extract are Ethan amine, Amino-octadic, and 4H-Pyran-4-one. It has an excellent inhibition efficiency (IE) of 83.078% at a concentration of 20 (mL/L) and a temperature of 298 (K). The extract was characterized by FTIR and GC MS, where the antibacterial was tested and the protective film was analyzed on the samples using FTIR spectra. The protective film formed on the metal surface is confirmed using an electrochemical study by Potentiostat, which revealed that this extract was a mixed-type inhibitor.
Highlights
- Wild clary extract is considered a good inhibitor of carbon steel
- The research methodology is a method for the principle of sustainability and recycling of waste.
- It is an easy and inexpensive extraction method.
