“…The usage of inhibitors is an effective way to protect iron against aggressive media [3][4][5][6]. The corrosion behavior of metal can be controlled by many natural extracts and synthetical compounds such as bamboo leaves [7], henna [8,9], coffee [10], Myrtus communis [11], Schiff bases [12][13][14], pyrimidine [15][16][17], thiazole [18][19][20], and imidazoline [21][22][23][24]. Chemical structures of those functional compounds are often related with O, S, N atoms, and multiple bonds which are all electron-rich groups [25,26].…”
