Study and Characterization of Chocolate B Clay on Adsorption of Heavy Metals (Lead and Zinc) in Bath Finite System

Abstract:

The clays are emerging as excellent alternative materials in the process of removing organic and inorganic contaminants, that due to it's physicochemical characteristics, it’s easy to obtain and also for low cost. The initial objective of this ( study was to characterize the clay Chocolate B by the techniques of X-ray diffraction (XRD) and cation exchange capacity (CEC). In addition, the testing of finite bath under certain conditions (pH, concentration) in order to better evaluate the efficiency of clay in the removal of heavy metals zinc and lead. It was used a factorial design 2² with addition at the central point, being evaluated the percentage removal (% Rem) and the removal capacity (q_eq) by Chocolate B Clay. It was observed that the Chocolate B clay belongs to the smectites group. The results have shown promise in the removal process of the metals zinc and lead by Chocolate B clay.
