Protective Efficiency of Bio-Inhibitors and Adsorption Isotherms: A Review
Subject area: Science,Engineering and Technology · Area of research: Corrosion
DOI: https://doi.org/10.64388/IREV9I5-1712089
Abstract
Corrosion inhibitors made of various non-chromates have been employed in place of ecologically dangerous chromates, and plant extracts are at the top of the list. Currently, a large number of compounds that are sold commercially harm human safety, whether used in the field, handled, or synthesised as inhibitors. Green corrosion inhibitors are compounds that are ecologically biocompatible, biodegradable, and nontoxic. Typically, they are composed of trash or extracts from natural plants, both of which are widely accessible in many nations. To prevent (initiation and/or propagation) the corrosion process, the majority of green inhibitor molecules used often consist of multiple bonds, aromatic rings, polar functional groups, and electronegative atoms such as P, N, S, or O that can work in coordination with metal cations to form protective layers(films) on the reinforcements' metallic surfaces. Numerous surface examination methods, including AFM, FTIR, UV, fluorescence spectra, and SEM, have been used to examine inhibitive films.
