| This paper presents a study of the influence of time on the mineral structure formation of GIS Na-P1 zeolite. Lightweight microspheres were used as a source of silica and aluminium. Material subjected to this study was synthesized on a quarter-technical scale using a prototype installation. Chemical, mineralogical, and textural properties of the material were determined by means of X-Ray diffraction (XRD), X-Ray fluorescence (XRF), scanning electron microscopy equipped with a system of chemical composition analysis based on energy dispersive X-ray (SEM–EDS), volumetric adsorption analyzer (ASAP 2020), Fourier transform infrared spectroscopy (FTIR) and particle size analyzer (PSA). Experimental calculations based on Miller indices show the interesting and indeed astonishing phenomenon of the lattice parameters ripening as a function of time. Both unit cell parameters (a, b, c and volume) and the amount of zeolite present increase with synthesis time. This process is clearly observed using the XRD and FTIR method. Structural, morphological and textural properties of the final product indicate that it could potentially be useful as an adsorbent for various types of environment pollution. |
