“…The use of corrosion inhibitors to protect metals and their alloys against corrosion had been accounted to be the best practical method [1]. A corrosion inhibitor is depicted as the substance that when added in small concentrations to a corrosive media reduces the corrosion rate of the metals [2,3].…”

“…[2][3][4] Generally, organic molecules containing hetero atoms (O, S, N), unsaturated bonds, p-electrons or polar functional groups can be expected to be excellent corrosion inhibitors. [5][6][7] Many compounds such as plant extracts, drugs, and synthetic organic molecules have been proven to have good corrosion inhibition effects. 8,9 It is generally believed that these inhibitor molecules protect the metal by adsorption on the substrate surface through donoracceptor interactions.…”

“…Inorganic anions provide passivation protection to metal surfaces through their incorporation into the oxide layer; the most widely used of these are: chromate (CrO 4 2− ), nitrate (NO 3 − ), molybdate (MoO 3 − ), phosphate (H 2 PO 4 − ) and silicates. Recently, the influence of organic, environmentally friendly corrosion inhibitors for zinc protection is increasingly being investigated [3,4].…”

Recently, the influence of organic, environmentally friendly corrosion inhibitors for zinc protection is increasingly being investigated [3,4]. One of these environmentally friendly corrosion inhibitors is L-tryptophan, an amino acid from the indole group, which has shown good properties in zinc protection in sodium chloride solution at a concentration of 1 × 10 −2 mol/L [5,6].…”
