The Inhibition Effect of Potassium Iodide on the Corrosion of Pure Iron in Sulphuric Acid

Year: 2014
Type: article
Abstract: The use of inorganic inhibitors as an alternative to organic compounds is based on the possibility of degradation of organic compounds with time and temperature. The inhibition effect of potassium iodide on the corrosion of pure iron in 0.5 M H2SO4has been studied by weight loss. It has been observed from the results that the inhibition efficiency (IE%) of KI increases from 82.17% to 97.51% with the increase in inhibitor concentration from 1·10−4to 2·10−3 M. The apparent activation energy ( Ea ) and the equilibrium constant of adsorption ( Kads ) were calculated. The adsorption of the inhibitor on the pure iron surface is in agreement with Langmuir adsorption isotherm.
