Abstract
This study explored the possibility of Schiff-base ligand compound, 2-acetylpyridine 4-ethyl-3-thiosemicarbazone (LH) and its organotin(IV) complex (BuSn(L)Cl2) as a corrosion inhibitor for mild steel in 1M hydrochloric acid (HCl) medium. The chemical structures of the synthesised compounds were confirmed by performing elemental analysis, FT-IR, UV-Vis, NMR spectroscopy, and X-ray crystallography diffraction study. The structure showed the LH served as a tridentate (N, N', S) donor to tin through its pyridyl, azomethine nitrogen, and thiolate sulphur. The corrosion inhibition characteristics of the free Schiff-base ligand and its organotin complex were studied by the standard weight loss method. They showed inhibition activity through adsorption, and this phenomenon was found to obey Langmuir adsorption isotherm. The inhibition efficiency of both compounds was found to increase as their concentration was increased from 1 to 3mM, but the efficiency achieved with the tin complex was greater, being 98.98% at 3mM concentration.
