Electrochemical Behaviour of Jatropha Curcas Plant Extract on Brass in Hydrochloric Acid Medium

Deepa Rani. P, Selvaraj. S

Abstract :

 The inhibition efficacy of Jatropha curcas leaves (JCL) extract on the corrosion of Brass (60/40) in 1N Hydro chloric acid environment is studied by potentiodynamic polarization and electrochemical impedance spec –troscopy (EIS) measurements. The inhibition efficiency is increased with increase of inhibitor concentration and achieved maximum of more than 80% for polarization as well as impedance measurements. Electrochemical measurements show that both polarization and charge transfer resistances increases with increase of inhibitor concentration. In bode phase plot, the increasing concentration of JCL inhibitor in hydrochloric acid solution results in more values of phase angle at high frequencies also suggested that, there was greater surface coverage and charge transfer resistance.
