Technical Article---Peer-Reviewed


The inhibition effect of Flectofenine on corrosion of mild steel in 1M HCl solution was investigated by using traditional weight loss method and electrochemical techniques at different concentrations and temperatures. Adsorption of the inhibitor follows a Langmuir adsorption isotherm studied at the temperatures of 303–333 K. The change in free energy and change in enthalpy explain the mode of the adsorption. Activation energy values, apparent enthalpy changes and apparent entropy changes explain the corrosion process. The mechanism of inhibition was discussed.
