Jujube Fruit Extract as an Ecological Inhibitor of Copper Corrosion in Hydrogen Chloride Environment

摘要

The purpose of the patent is to study the inhibitory effect of a new environmental inhibitor on copper corrosion in chlorides. This work is particularly concerned with assessing the mechanism of copper corrosion in hexachlorocyclohexane environment by jujube extracts from the genus Zizyphus (FJPZL). GravimetryThe effects of concentration and temperature on the inhibitory activity of extracts (FJPZL) were studied. Scanning electron microscopy (SEM) was used to analyze the surface states and compositions before and after adding inhibitors.Atomic Force Microscopy and X-EDS Microscope: The inhibition efficiency of hydrogen chloride containing 2g/l concentration (FJPZL) on copper corrosion reached 92% at 27 degree C. Electrochemical test results Key words: inhibitors, corrosion, acids, extracts
