“…Tannin from plant source already in use as corrosion inhibitor in industry example Mimose tannin from wattle tree in acidic media, components of rust converters, pigments in paint coating, corrosion inhibitor of reinforcing steel in concrete, chemical cleaning agents for removing iron-based deposits and oxygen scavengers for boiler water treatment systems. Tannin contain four flavonoid monomer namely: catechin, epitechin, epigallocatechin and epicatechin gallate showed in FIGURE 2 tannin exhibited good anticorrosive properties due to its flavonoid monomer are potential corrosion inhibitors for steel in acidic medium [7]. Mechanism of Mimosa tannin adsorption was investigated by Martinez.…”

Abstract. Tannin was extracted from gelam bark and used to produce corrosion inhibitor for mild steel. Tannin was extracted from gelam bark using 70% aqueous acetone for 6 hour. Tannin powder was characterization using fourier transform infrared spectroscopy to analyse chemical component in tannin and Scanning electron microscope (SEM) for tannin physical structure. The tannin effect on the corrosion inhibition of mild steel has been investigated in 1Mol HCl solution for 6 hour followed ASTM. The weight loss method were applied to study the mild steel corrosion behavior in the present and absend of different concentration of tannin (250, 300, 350 )ppm. Tannin act good inhibitor as corrosion inhibitor for mild steel in acid medium. Surface morphology of carbon steel with and without inhibitor was investigated by scanning electron microscopy
