Abstract
Glauconite and kaolin are used as adsorbent materials for iron removal from synthetic solutions. Different concentrations of iron solutions have been prepared (10, 20 and 30 mg/L). Different dose of glauconite and kaolin were added (0.1, 0.55 and 1.0 g). Statistical design was used to determine the optimum conditions of iron adsorption on glauconite and kaolin. It is shown that glauconite has high adsorption for iron reaching to 95% while kaolin has lower adsorption for iron. Physical and chemical characterization of glauconite and kaolin was tested. High surface area of glauconite (19.8 m2/g) compared to kaolin (5.4 m2/g) explains its high removal efficiency.
