چکیده
|
Green corrosion inhibitors are biodegradable. some research groups have reported the successful use of natural substances to inhibit the corrosion of metals in acidic and alkaline environments. among the various green inhibitors, plant extracts are becoming increasingly popular. in this study, the inhibition and adsorption properties of moringa oleifera (mo) leaf extract as corrosion inhibitors of xc70 carbon steel in 1m hcl were investigated using the weight loss method to monitor corrosion. the inhibition efficiency increases with increasing concentration of the mo extract, with the maximum percentage corrosion inhibition efficiency being 97.60% at 60(v/v). the adsorption mechanism between the extract and the carbon steel substrate is shown to obey the langmuir and temkin isotherms.
