Abstract
The corrosion inhibition of carbon steel (CS) in 3 M HCl was thoroughly investigated in the presence and absence of areca plant extracts as a green corrosion inhibitor. The effect of solution temperature and different amounts of areca plant extracts was examined through gasometric, colorimeter and atomic absorption spectroscopy techniques. Surface studies were screened by scanning electron microscopy (SEM) technique. The results of these techniques show that areca plant extracts (arecanut husk extract, arecanut seed extract and areca flower extract) behave as a nontoxic corrosion inhibitor for CS in 3 M HCl solution. Areca plant extract (arecanut husk extract, arecanut seed extract and areca flower extracts) shows maximum protection efficiency at 4 g/L extract amount.
