N-SALICYLIDENE-4-CHLOROANILINE AS PROTECTOR MATERIAL IN PREVENTING CORROSION PHENOMENON IN ACIDIC MEDIUM
Keywords:
Acidic medium, corrosion inhibitor, mild steel, Schiff baseAbstract
Corrosion inhibitor was used for protection of metals and alloys in dealing with corrosion
problems. Recently, Schiff base ligands have been reported as effective corrosion inhibitors due
to the presence of Nitrogen, Sulphur, Oxygen, C=N group, and π-bond that can form a covalent
bond and help in reducing corrosion rate. This research introduces N-salicylidene-4-
chloroaniline as a protector material in preventing corrosion phenomenon (corrosion inhibitor)
in our surrounding. The structure of this compound was characterised using CHN elemental
analysis, FTIR, 1HNMR, and UV-Vis spectroscopy. The combination results proved that this
compound has C=N group and π-bond, which are good inhibitor properties. The corrosion
inhibitor study in 1 M HCl solution was conducted via weight loss method. Results showed that
the increase of inhibitor concentration will increase the inhibition efficiency and vice versa to
immersion time, where the inhibition efficiency decreases with a longer exposure of mild steel
in acidic medium. The conducted experiment shows that the percentage of inhibition efficiency
is 80.0% in 78 hours reaction. It showed that the ligand can act as a good corrosion inhibitor
in 0.1 M concentration, which slows the corrosion rate on the metal surface.
