Kinetic study of copper adsorption onto Moroccan Illitic and kaolinite clay

Abstract

In order to optimize and reduce the rate of inorganic micropollutants rejected by various metal installations, according to wastewater treatment standards and environmental protection, we proceeded by studying the adsorption of heavy metals such as copper by using the Illitic and Kaolinite Clay from Moroccan (IKCM) of El Oulja-Salé region. We are interested in the analysis of the physicochemical parameters influencing the removal of heavy metals (time effect, mass effect absorbent, concentration of initial copper solutions effect, stirring rate effect and the solution’s pH). The results of this study was produced by the characterization technique of X-Ray Diffraction (XRD), the Atomic Adsorption Spectroscopy (AAS) and linear forms Langmuir isotherm and Frendlich models which show that the binding and removal copper by this clay is fast with increasing parameters mentioned previously.
