Adsorption of Water Heavy Metals onto Natural Clay

Shaymaa M. A. Hamdy

Abstract :

Extensive endeavors are mandatory to economically remove the heavy metals from contaminated water, among viable options the natural clay. Adsorption capacity of clay materials towards adsorption of heavy metals sequences are greatly influenced by operating conditions. In these study competitive adsorptions of heavy metals ions (Zn and Pb) on natural clay was investigated in order to understand the influence of initial pH on the clay adsorption capacity of heavy metals. Batch adsorption experiments were performed at six different pH values (4, 5, 6, 7, 8, and 9) with 10g of clay for each value. The results indicate that the best removal was obtained at pH 5. In another experiments the clay weight was changed to six values (4, 6, 8, 10, 12 and 14) in each value the pH adjusted to 5 . The best removal obtained at clay weight 8g and stayed equal for (10,12 and 14 )g had the lowest concentration of Zn, but in Pb all clays treatments was free from Pb.
