Abstract: The natural-green corrosion inhibitor is extracted from cilantro seeds through Soxhlet Extraction, and its inhibition performance on Zn in hydrochloric acid solution is evaluated by a static gravimetric method and electrochemical method. Together with the detailed discussion on inhibitor concentration, corrosive immersion time and temperature effects of inhibitive efficiency, we conclude that this corrosion inhibitor performs good on Zn. The maximum inhibitive efficiency reached and the surface adsorption of Zn conforms to Langmuir Adsorption Isotherm. The EIS shows that there’s an obvious inhibition of charge transfer after the performance of surface adsorption of Zn. Comprehensively, OSLE is a kind of mixed-inhibiting corrosion inhibitor.
Key Words: Cilantro seeds; Soxhlet Extraction; Corrosion inhibitor; Inhibition performance |
