The main goal of this work was to synthesize and evaluate the effect of dehydration temperature on the potential application of hydroxy sodalite zeolite membrane. Hydroxy sodalite zeolite membranes were synthesized via direct hydrothermal method onto a tubular alumina support without seeding in a hot air oven. The synthesized membranes were characterized by X-ray diffraction (XRD) and scanning ...

mineral dissolution and precipitation may occur. The effect of alkaline solutions on the transformation of Buried waste storage tanks at the USDOE Hanford Reservation clay minerals has been the subject of intensive research in Washington State have released solutions containing high concentrations of Na, OH, NO3, and Al into the vadose zone. When such (Cuadros and Linares, 1996; Bauer and Berge...

In this research, the zeolite sodalite, as an inorganic ion exchange material, was chemically produced in the template-free synthesis and evaluated in order to facilitate the sorption of strontium ions from aqueous solutions in batch operations onto acid treated zeolite with dilute H2SO4 solutions. The following indicates what the batch experiments included: a sorbent amount of 0.25 g in 100 mL...

In this paper, a novel nano crystalline sodalite was synthesized and characterized by XRF, XRD, SEM and FTIR analysis. Cu2O nanoparticles (30-60 nm) were loaded on nano zeolite bed and utilized as an adsorbent to remove dimethyl phthalate. The SEM-EDX of modified zeolite indicates that the amount of copper loading on the zeolite was 4.5 wt%. Modified nano zeolite was used as an effective adsorb...

Faujasite (FAU) zeolites (with Si/Al ratio of ca. 1.7) undergo mild dealumination at moderate ion exchange conditions (0.01 to 0.6 M NH4NO3 solutions) resulting in protons circumscribed by sodalite cages becoming accessible for reaction without conspicuous changes bulk crystallinity. The (HSOD) supercages (HSUP) can be systematically manipulated from 0 1 adjusting ammonium concentrations used e...

The reactions to produce liquid biofuels from a palm fatty acid distillate (PFAD) under hydrogen absence were carried out using 10 wt% NiO/zeolite (Ni/Zeo), Co3O4/zeolite (Co/Zeo), and (NiO + Co3O4)/zeolite (NiCo/Zeo) as catalysts. zeolite was synthesized by thermal chemical treatment natural clay, obtaining A sodalite mixture. Catalytic activity evaluated function of reaction temperature (250,...

This study investigated the one-pot hydrothermal synthesis of mixed-phase ion-exchangers from waste amber container glass and three different aluminium sources (Si/Al = 2) in 4.5 M NaOH(aq) at 100 °C. Reaction products were characterised by X-ray diffraction analysis, Fourier transform infrared spectroscopy, 27Al 29Si magic angle spinning nuclear magnetic resonance spectroscopy scanning electro...

Sodalite Na8(Al6Si6O24)Cl2 (space group P4¯3n) is an important mineral belonging to the zeolite group, with several and manyfold fundamental technological applications. Despite interest in this from different disciplines, very little known regarding its high-pressure elastic properties. The present study aims at filling knowledge gap, reporting equation of state moduli sodalite calculated a wid...

Topological characterization of 3D molecular structures is an emerging study area in theoretical and computational chemistry. These structural descriptors are used a variety domains, including chemical graph theory, drug delivery, nanomaterial characterization. Quantitative can be to characterize the physical properties given compound. indices graphs numerical quantities that allow us collect i...
