摘要：
Using weight loss method, the pomegranate peel extract (PPE), that is a green corrosion inhibitors, have been studied in the corrosion inhibition of Q235A steel in 1M hydrochloric acid solution at 30 degrees C, 45 degrees C, 60 degrees C, respectively. The inhibition rate of extract varies with the extraction concentration in the range of 10 similar to 1000mg / L, up to 92.7%. Extract inhibits corrosion through adsorption mechanisms. Besides polyphenols hydroxyl and ether groups can slow down corrosion by capturing H+. Polyphenols can remove the dissolved O-2, and curb oxygen reducing corrosion. PPE is antifungal active against TGB and FB, but not so active against SRB.
