Characterization of a Zeolite Obtained by Means of a Hydrothermal Synthesis Process
摘要
ZeolitesZeolite are aluminosilicates with porous structureStructure. Due to their cation exchange properties, they are widely used for the treatment of water contaminated with metals. In this research a Mexican expanded perliteExpanded perlite was used to obtain synthetic zeoliteZeolite by the hydrothermal method, the material was characterized by XRF, XRD, FTIRFourier transform infra-red (FTIR), SEMScattering electron microscopy (SEM) techniques. A hydrothermal reactor with a 20 ml PTFE vessel, 1 g of material and 17 ml of NaOH solution were added, then placed in oven. The variables evaluated were NaOH concentration, maintained temperature and time of heating. The type of zeolitesZeolite obtained were zeoliteZeolite Na-P1, cancrinite, sodalite, zeoliteZeolite type A and zeoliteZeolite type Y.
