Synthesis of high value-added Na–P1 and Na-FAU zeolites using waste glass from fluorescent tubes and aluminum scraps

Résumé

The present work reports the feasibility of valorizing waste glass and aluminum scraps into zeotype materials. The raw materials were reacted hydrothermally at 60°C using alkaline fusion prior to hydrothermal treatment. The obtained powders were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), electron microscopy (SEM) and magic angle spinning nuclear magnetic resonance (MAS NMR) of 27 Al and 29 Si nuclei. The influence of some parameters like alkalinity, reaction time and particle size on the nature of obtained zeolites has been also studied. The characterization methods demonstrated that the final products are aluminosilicate materials with a high cation exchange capacity containing Na-FAU and Na-P1 zeolites. The above results show that valorization of waste glass and aluminum scraps to obtain Na-FAU and NaP1 zeolites is possible and can be a sustainable alternative to the traditional synthesis methods.
