Evaluation of the Performance of Sheng (Tragopogon Buphthalmos Boiss) Extract as a Green Corrosion Inhibitor in High Concentration Hydrochloric Acid Solutions, M.Sc. Thesis Sharif University of Technology ; Afshar, Abdollah (Supervisor)
Abstract
In this study, the extract of Tragopogon buphthalmos Boiss was investigated as a green or environmentally friendly corrosion inhibitor for mild carbon steels in high concentration hydrochloric acid solutions. Tragopogon buphthalmos Boiss was extracted using the extraction method of digestion at 50 ° C assisted by ultrasonic bath. Water-ethanol-acetone solvents were used in ratios of 30:35:35, respectively. The ratio of plant volume to solvent volume was one to ten. The container containing the extract was placed in a bath water at 50 ° C until the extract was in the form of gum, then stored at -15 ° C In a freezer. Infrared Fourier transform spectroscopy (FTIR) was used to determine the...
