چکیده

In this work, hazelnut hull is suggested as an adsorbent to remove Fe(III) from aqueous solutions. The removal of Fe(III) was investigated as a function of adsorbate initial concentration, solution initial pH, temperature, contact time, and the adsorbent amount. Under optimum conditions (pH 3, adsorbent amount 0.6g, temperature 30C, time 70min), the maximum removal of Fe(III) cations was 83.5%. Both the Langmuir and Freundlich isotherms were suitable for describing the adsorption of Fe(III) on hazelnut hull. The capacity of the hazelnut hull for adsorption of Fe(III) was 13.59mg/g.
