An overview of corrosion and its control by the surfactants: a mini-review

Le résumé fourni par la source

In recent years, studies of the effectiveness of various surfactant inhibitors in inhibiting corrosion have been published. In acid media, surfactants have generally demonstrated inhibitory efficiency (IE%) ranging from roughly 60% to over 98%. The literature on the cationic, anionic, zwitter ionic, neutral, and Gemini surfactants used to prevent steel corrosion in a range of acidic environments is compiled in this review. Also, the relationship between the amphiphilic nature of surfactants and a lower corrosion rate when using various surfactant classes. The surfactant structures, corrosion rates (CR), free energy of adsorption (ΔG°ads), and acid medium-dependent inhibition efficiencies (IE%) are highlighted. By indicating the connection between surfactants’ molecular structure and adsorption mechanisms, the study presents the most reliable quantitative evaluation of surfactants’ effectiveness as corrosion inhibitors in a range of environmental media. The fact that the majority of inhibitors followed Langmuir adsorption isotherm suggested a systematic adsorption mechanism.
