Single Component Adsorption of Nickel, Cadmium, Copper and Lead from Aqueous Solution Using Aswan Clay
Taha M. A. Razek
Abstract: Metals discharged to wastewater pose a great threat to environment. Treatment for such metals contaminated wastewater is a must. Aswan clay (AC) was tested as adsorbent for the adsorption of Ni (II), Pb (II), Cd (II) and Cu (II) from aqueous solutions. Batch scale experiments were carried out to study the main adsorption parameters such as pH, adsorbent concentration, initial adsorbate concentration, and kinetics of biosorption. The aforementioned elements were removed using AC at a percentage of 94.05, 92.36, 92.83 and 97.41 % for Cu (II), Cd (II), Ni (II) and Pb (II), respectively. The effectiveness of the studied biosorbent was demonstrated using wastewater samples emanating from electroplating shops and ceramic industry wastewater.
