Electrochemical kinetics, molecular dynamics, adsorption and anticorrosion behavior of melatonin biomolecule on steel surface in acidic medium.

Electrochemical, anticorrosion and adsorption behaviour of bio-based melatonin (MEL) in 5% HCl solution was investigated by experimental and theoretical approaches. MEL was found to possess high adsorptive capacity for steel surface and inhibits the acid corrosion. With a concentration of 10 mM, inhibition efficiency of 98.
