چکیده انگلیسی
Bistorta Officinalis extract was thoroughly characterized as an effective green inhibitor for prevention of corrosion and scale formation problems in cooling water system. Electrochemical impedance spectroscopy, DC polarization, weight loss measurement and UV-Vis spectroscopy have been conducted to investigate the mechanism and performance of the proposed inhibitor. The results of this study demonstrated the high corrosion inhibition performance of Bistorta Officinalis extract in cooling water. It was revealed that the inhibition action of this extract is due to adsorption of insoluble Fe2+ complexes over the steel surface which obeys the Langmuir adsorption isotherm and behaves as a mixed-type film forming corrosion inhibitor. In addition, the Bistorta Officinalis extract exhibited an excellent scale inhibition performance of 99.5% which make it an ideal material to prevent the scale formation in cooling water. Accordingly, the Bistorta Officinalis extract could be proposed for effective treatment of cooling water systems.
