Abstract

Cuminum cyminum (Jeeru) seeds extract studied for its inhibitory effect on corrosion of brass in different concentration of HNO3 solution using weight loss method, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The inhibition efficiency increases with increase in extract concentration but decreases with increase in temperature. The temperature study on corrosion behaviour in temperature range 313-333K at 0.1 M nitric acid. The value of Free energy of adsorption (G0ads), Heat of adsorption (Qads), Energy of Activation (Ea), Enthalpy of adsorption (H0ads) and Entropy of adsorption (S0ads) were calculated. Adsorption studies revealed that Langmuir adsorption isotherm is the best adsorption model applicable to the adsorption of cuminum cyminum extract on brass surface. Present study indicates that cuminum cyminum seeds extract is a good inhibitor for the corrosion of brass in nitric acid medium.

Key Words

Corrosion, Cuminum cyminum, Langmuir, Nitric acid, Potentiodynamic polarization, Electrochemical impedance spectroscopy.
