Abstract

A corrosion inhibitor composition , which includes i ) an aqueous alcohol base fluid , ii ) a mixture of at least three polysaccharides selected from carboxymethyl cellulose , gum arabic , pectin , a salt of alginic acid , chitosan , dextran , hydroxyethyl cellulose , and soluble starch , with each poly saccharide that is present in the mixture being present in an amount of 0.05 to 0.5 wt . % , based on a total weight of the corrosion inhibitor composition , iii ) silver nanoparticles , and iv ) a pineapple leaves extract . A method of inhibiting corrosion of metal during acid cleaning / pickling whereby the metal is treated with an acidic treatment fluid containing an acid and the corrosion inhibitor composition .
