Iron Removal from Ground Water using Egyptian Cost-Effective Clay Minerals

Glauconite and kaolin used as an adsorbent material 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 reach 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 m 2 /g compared to kaolin 5.4 m 2 /g explain its high removal efficiency.
