Termite Frass Lignin: A Long-Term Source for Anticorrosive Uses

Alison Parker

The current study describes a long-term supply of lignin derived from termite frass. Lignin was extracted using Klason's method and tested for inhibitory efficiency using polarisation tests. Electrochemical impedance spectroscopy was used to analyse the electrochemical performance of the coated sample on carbon steel. In a corrosive environment, the anticorrosive property was found (0.1 M NaOH and 0.5 M NaOH). The morphological examination of the surface of both bare metal and lignin-coated metals was recorded using atomic force microscopy (AFM), scanning electron microscopy (SEM), and energy-dispersive X-Ray spectroscopy before and after exposure to the corrosive environment (EDX).
