This study presents the synthesis of zeolites derived from coal fly ash (CFA) using fusion-assisted alkaline hydrothermal method. The were synthesized by combining CFA and NaOH at a molar ratio 1:1.2 under fusion temperatures 500, 600, 700 °C. Subsequently, obtained subjected to further modifications through incorporation magnetic (Fe3O4) silver (Ag0) nanoparticles (NPs). Fe3O4 NPs introduced c...

Zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. Zeolites with PHI and SOD structure are so common and applicable for this purpose. Hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as Sr, Pb, Zn, Cu and Rb. There is not any pure natura...

In this study, clay and non-clay minerals in the cement of Cretaceous volcanogenic–sedimentary rocks from bottom marginal seas north-western Pacific Ocean adjacent areas were studied. Corrensite mixed-layer chlorite–smectite, rectorite illite–smectite, chlorite, swelling chlorite (?), illite, kaolinite, smectite calcite, ankerite, barite, gypsum, epsomite, zeolites (laumontite, analcime, stilbi...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...

Abstract The paragenesis and composition of bavenite–bohseite were investigated in fifteen granitic pegmatites from the Bohemian Massif, Czech Republic. Three types distinct their relation to primary Be precursors, mineral assemblages, morphology origin recognised: (1) hydrothermal crystallised miarolitic pockets residual pegmatite fluids; secondary two types: (2) a proximal type restricted spa...
