QSAR Study of the Adsorption Mechanism of Ascorbic Acid towards Iron in Alkaline Media

Abstract:

A significant correlation was obtained between corrosion inhibition efficiency and the molecular structure of ascorbic acid, using the Quantitative Structure Activity Relationship (QSAR) approach based on a multivariate nonlinear regression technique. It is proposed that inhibitor molecules attach to iron surface by means of chemical adsorption. The considerations leading to this assumption were confirmed by ATR FTIR spectroscopy.
