Abstract EN
The aim of this paper is the synthesis of a Faujasite type zeolite: 9SiO2: Al2O3: 3Na2O: 120H2O and study its ability to remove heavy metals from an industrial effluent.
Characterization of the zeolite was carried out by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM).
The study of the elimination of ten heavy metals on an aqueous effluent, taken from the industrial zone of Bounoua (Algeria), shows that the synthesized zeolite is able to eliminate nearly 40% of the analyzed heavy metals.
the results demonstrate a removal rates of metals in a descreasing order, as following: Cd > Mn > Sn > Fe > Cr > Ni > Pb > Mg > Zn > Cu.
Cadmium is the most adsorbed metal with a rate of 86.47 % and copper takes the last position with a removal rate of 19.27 %.
The kinetics and isotherms study of adsorbtion of cadmium by zeolite shows that the adsorption is managed by kinetics of the pseudo-second order and the Langmuir isotherm represents better the adsorption of this metal.
The study demonstrates that, besides the economy, zeolite facilitates the process of adsorbtion.
Moreover, the zeolite is very efficient and reliable material to eliminate the heavy metals and to mitigate the problems of pollution of the environment caused by the industrial activities.
