The Schiff base ligands are characterized by using elemental analysis, infrared spectroscopy, JH NMR spectroscopy and melting point determination. The compounds are examined for their inhibitive effect toward corrosion of copper metal in 1M hydrochloric acid by using the weight loss method. The effect of different concentrations of each compound, ranging from 0.01M to 0.0001M toward inhibiting corrosion is investigated. The results show the most effective Schiff base as an inhibitor of corrosion is MeO-salen at the concentration 0.01M with inhibiting efficiency of 64.90%. 2010 Thesis https://ir.uitm.edu.my/id/eprint/103871/ https://ir.uitm.edu.my/id/eprint/103871/1/103871.pdf text en public degree Universiti Teknologi MARA (UiTM) Faculty of Applied Sciences Bahron, Hadariah
