Abstract
A picking solution for iron and steel comprises a mixture selected from organic acids containing hydroxy groups and salts or esters of such acids, at least one dissolving rust and scale and the other forming a soluble complex with iron. The pH is 1 to 9 (preferably 3 to 6) and is adjusted by adding sulphuric acid. A preferred solution comprises, glycolic acid, heptagluconic acid, and E.D.T.A. Other acids referred to are citric, hydroxyacetic, gluconic, malonic, tartaric, methyl tartronic Oxidizing agents e.g. alkali and ammonium nitrate, nitrite, hypochlorate or hypochlorite, and fluorides may also be added.
