Investigations Properties on the Corrosion Inhibition of Kala Bansa Leaf Extract on Mild Steel in an Acidic Environment
Abstract
Different Ct of KBE from its leaves were used to study its effect on MS corrosion resistance.Electrochemical methods such as PDP, EIS and WL tests were herein used.Experimental results showed that, with higher Ct of KB, its IE(%) increased.The highest corrosion IE(%) of 98.41, at 1600 ppm KBE in a 0.5 M H2SO4 solution, was obtained.The inhibitor's adsorption onto the MS surface was excellent, since it created a monolayer.KBE´s adsorption mechanism obeyed Langmuir's isotherm.SEM analysis established the development of a protective layer on the MS surface.
