“…This was agreed upon by Bashir et al [10] and Sanaei et al [87]. Examples of phytochemicals are tannins, flavonoids, and saponins [42]. Figures 9-11 show the backbone units of tannins and flavonoids, and the chemical structure of saponins, respectively.…”

“…This was highlighted by Anupama et al [40], Fidrusli et al [41], and Vorobyova et al [24]. Furthermore, Omotosho et al [42] concurred and added that the aftermath might be due to the nitrites, chromates, and benzoates. Hassan et al [9] agreed and explained that most inhibitors have been found to be nondegradable and poisonous.…”

Acid corrosion is a problem pertaining to corrosion that involves an acid solution. It is important to treat metal to preserve its integrity. Thus, acids are utilized to clean and treat metal surfaces. In return, this may lead to over-etching and metal degradation. Corrosion inhibitors were introduced as a solution for the issue. However, there are some problems associated with the usage of conventional corrosion inhibitors. Traces of nitrites and chromates that are present in the inhibitors may lead to serious health and environmental issues. As a solution, organic green corrosion inhibitors have been studied to replace the conventional corrosion inhibitors. These inhibitor molecules form a protective layer on top of the metal surface to suppress metal dissolution when added to the acid solution. This process prevents direct contact between the metal surfaces and the acid environment. This study explores the usage of natural resources and biomass wastes as the basis for organic green corrosion inhibitors. This study also provides some suggestions for new biomass wastes that can be studied as new organic corrosion inhibitors, and it is aimed at opening the perspective of researchers on exploring new organic inhibitors by using natural resources and biomass wastes.
