Uncaria Gambir As Natural Corrosion Inhibitor For Mild Steel In Acidic Solution
Uncaria gambir, a native Southeast Asia herbal plant has been characterized and studied as a mild steel corrosion inhibitor in acidic media. It was revealed that ethyl acetate gambir extract gave the highest condensed tannin, phenol and flavonoid content compared with other solvent extracts. Quantif...
