Green Approach To Corrosion Inhibition Of Aluminium By Senna Auriculata Leaves Extract In 1 N NaOH Solution
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 1
Abstract
Corrosion inhibition of aluminium in 1N NaOH by leaves extract of Senna auriculata (SL) was studied using chemical and electrochemical techniques at 30-60ï‚°C. It was found that the leaves of Senna auriculata inhibited the base induced corrosion of aluminium.The inhibition efficiency increasing with increase in concentration of SL extract and reached the maximum of 76.2% that decreases with rise in temperature. The adsorption of SL on metal surface obeys Langmuir adsorption isotherm. Polarization measurements showed that SL extract acted as mixed type inhibitor. The surface morphology of aluminium in the absence and presence of SL extract in 1N NaOH solution, was studied using scanning electron microscopy. Results obtained from chemical and electrochemical techniques were in good agreement. Thermodynamic parameters such as activation energy and free energy of adsorption was also calculated to explain the inhibition mechanism.
