ABSTRACT
Corrosion is a natural process that occurs when metals and alloys react with the environment [1–3]. It can cause stresses and damage to metal structures and equipment [4–7], leading to expensive repairs and mitigations [8]. An inhibitor can protect metals from corroding, especially in acidic environments [9,10]. Inorganic corrosion inhibitors, such as chromates, cobalt, cadmium, tetraborates, and other heavy metals, and organic inhibitors, such as imidazole, thiazole, pyrazole, pyrimidine, and hydrazine, have been effective in preventing corrosion [1,9,11]. However, these inhibitors are toxic and have harmful effects on the environment and living organisms [9,11,12]. Therefore, there has been a growing interest in using biopolymers as alternative corrosion inhibitors [13].
