Research Progress of Extraction and Inhibition of Natural Corrosion Inhibitor

Abstract

In this work，the methods for extracting natural corrosion inhibitors including immersion extraction，heating reflux，Soxhlet extraction and ultrasonic extraction were introduced，and the natural corrosion inhibitors extracted from four kinds of raw materials such as seed plants，algae plants，medicinal plants and discarded fruit peels by domestic and foreign researchers were summarized.In addition，the synergistic effect，active ingredient and corrosion inhibition mechanisms of various natural corrosion inhibitors were introduced，and the development and application prospects of natural corrosion inhibitors were prospected.
