| Popis: | The present work aimed to achieve mineralogical and spectroscopic characterization of the Late Cretaceous clays of Aleg formation (Coniacian-Lower Campanian system), Tunisia, for the removal of several toxic metals in aqueous system. The collected clay samples were first characterized by different techniques including X-ray fluorescence (XRF), thermal analysis (TG/TDA), X-ray diffraction (XRD), Fourier transform infrared (FTIR) and scanning electron microscopy (SEM). Results showed that the natural clay samples are mainly composed of silica, alumina, iron, calcium and magnesium oxides. The sorbents are mainly mesoporous materials with modest specific surface area of |
