Comparative studies of amino acid and soybean as corrosion inhibitors of steel in hydrochloric acid / Nurul Izzati Rosli

Amino Acid and Soybean potentials as organic corrosion inhibitors were examined through a few tests conducted. Sample characterization is performed to analyze compounds contained in soybean and glycine by using FTIR and UV-VIS. From FTIR spectrum obtained both soybean and glycine has N-H and C-N bon...
