Corrosion inhibition, Adsorption,, Activation energy, Heat of AdsorptionAbstract
Senna alata leaves, root and stem extracts respectively were studied as corrosion inhibitor for mild steel in 1M HCl at temperatures 30oC, 50oC and 60oC using gravimetric technique. The extracts were found to inhibit corrosion of mild steel in acidic medium. The inhibition efficiency increased with increase in concentration of the extracts, with the leaves and stem extracts showing maximum inhibition efficiency in 800mgl-1 of the extracts. The inhibition efficiency decreased with rise in temperature between the temperature of 30oC and 50oC but increased with rise in temperature between 50oC to 60oC suggesting a mixed adsorption mechanism of chemisorptions/physisorption of the plant extract on the mild steel surface. The trend in calculated values of apparent activation
energies, free energy of adsorption and heat of adsorption provided evidence of adsorption and chemisorption mechanism was confirmed. Adsorption of extract molecules on mild steel surface was found to fit into Langmuir adsorption isotherm.
