Zeolite synthesis in basic media using expanded perlite and its application in Rhodamine B adsorption
In this work, expanded perlite was employed as a Si and Al source in zeolite synthesis. The products obtained were mixtures of three zeolitic topologies identified by X-ray diffraction and scanning electron microscopy. The zeolite OFF presented elongated prism morphology and the zeolites GIS and ERI...

| Sumario: | In this work, expanded perlite was employed as a Si and Al source in zeolite synthesis. The products obtained were mixtures of three zeolitic topologies identified by X-ray diffraction and scanning electron microscopy. The zeolite OFF presented elongated prism morphology and the zeolites GIS and ERI appeared as crystal intergrowths. The products and the expanded perlite were used in a Rhodamine B adsorption study . The zeolitic mixture turned out to be a better adsorber than the expanded perlite, obtaining an efficiency of 90% up to 2 min and an equilibrium efficiency of 72% after 5 min |
