Abstract | ||||
IN this study, the ability of chitosan (β (1→4) linkage of 2-acetamido-2-deoxy-β-D glucose] to remove mercury from water samples was studied. Chitosan was characterized by FT-IR, XRD and FE-SEM. The Hg (II) uptake capacity was studied; different factors were considered such as pH, contact time, adsorbent dose, metal ion concentration. From the obtained results, it was found that chitosan exhibited a maximum uptake capacity of 32.83 mg/g under the investigated conditions. The uptake process was found to follow Frundlish Adsorption Isotherm and Pseudo Second Order Kinetics | ||||
