Organic and inorganic corrosion inhibitors: A comparison

Organic and inorganic compounds are widely used as corrosion inhibitors. It is important to mention that most of the inorganic compounds are toxic and non-environmental friendly; therefore, their current use as corrosion inhibitors is strictly inhibited because of the increasing ecological awareness and strict environmental regulations. Most of the organic compounds become effective by adsorbing on the metallic surface. Adsorption of the organic compounds mostly follows the Langmuir adsorption isotherm model. Polar functional groups and multiple bonds act as adsorption centers during the metal inhibitor interactions. Present chapter deals with the comparison of various aspects of corrosion inhibition using organic and inorganic corrosion inhibitors. © 2022 John Wiley & Sons, Inc.
