Feasibility Study of the Properties of Clay Chocobofe Removal of Lead in Synthetic Wastewater

Abstract:

As minimization process control pollution by heavy metals, adsorption can play an important environmental role. Therefore, many adsorbents can be used as effective alternatives. This work presents a study that aims to evaluate the removal of lead in liquid effluent through adsorption process using a finite bath system and with the adsorbent clay Chocobofe. The clay in its natural form was characterized by the techniques of X-Ray Diffraction (XRD), Cation Exchange Capacity (CEC), Chemical Analysis by X-Ray Spectrometry by Energy Dispersive (EDX), moreover, the natural clay was subjected to test adsorption capacity to analyze the behavior the same in certain organic solvents. Was performed to assess the effectiveness of the natural clay in the process of removal of Pb²⁺ present in solutions based on a factorial design 2³ + 3 replicates at the central point, with the analysis variables solution pH (3.0, 4.0 and 5.0) and the initial concentration of lead (10, 30 and 50 ppm). The studies showed this material as promising in the removal of Pb²⁺ ions in synthetic wastewater and that the adsorption capacity showed that the organic solvents tested.
