Substituents effect on corrosion inhibition performance of organic compounds in aggressive ionic solutions: A review
Chandrabhan Verma,Lukman O. Olasunkanmi,Lukman O. Olasunkanmi,Eno E. Ebenso,M.A. Quraishi,M.A. Quraishi +5 more
TL;DR: In this article, a simplified model for the prediction of relative performances of chemisorbed organic molecules as corrosion inhibitors is presented, which holds that electron donating substituents promote inhibition effectiveness while electron withdrawing substituent reduces corrosion inhibition potential.
