Abstract
In this study, we reported a simple and easy process for zeolite synthesis using waste glass and aluminum scraps. The silica source was obtained from glass of the end-of-life fluorescent tubes and aluminum source was scraps collected from aluminum workshop in the region of Sfax, Tunisia. The zeolitic materials were prepared by hydrothermal treatment at 60 °C for 6 days using 10 g of glass powder mixed with sodium aluminate solution prepared from aluminum scraps. In order to optimize the nature of the recovered zeolites, reaction time, particle size, aluminum concentration and liquid/solid ratio were monitored. T The starting materials and the prepared zeolites were characterized by X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Nuclear Magnetic Resonance (NMR) of 27 Al and 29 Si nuclei. The characterization techniques demonstrated that the recovered solid after 6 days of crystallization at 60 °C using different particle sizes (ø <63 µm, ø <125 µm, ø <325 µm) was zeolite Na-LTA contaminated with small quantity of Na-P1.
