nickel doped tio2 nano particles (1% w/w) were prepared and immobilized on nax zeolite and after characterization by x-ray diffraction (xrd) and scanning electron microscopy (sem) used as photo catalyts for degradation of orange g. the xrd patterns show that the supported tio2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the increase of tio2 loading. sc...

in this scientific research, for the first time, the removal of radioactive strontium-90 (90sr) by γ-mno2-aga zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as ph, temperature, adsorbent amount and the contact time that are examined from drinking water of ramsar city and monitored via ultra low-level liquid scintillation counting (lsc) technique. pri...

Calcium Oxide (CaO) loaded on zeolite was categorized as a heterogeneous catalyst. The utilization of CaO catalyst could be implemented in catalytic pyrolysis enhance gaseous production. In this paper, CaSO4.2H2O is an active site embedded natural zeolite, and the activity CaO-Zeolite synthesized by sonochemical impregnation-assisted drying process calcination. stirrer impregnation method used ...

Growth, nutrient balance, plasma ammonia levels and urinary p-cresol excretion were evaluated in growing pigs fed diets containing various levels of zeolite A or clinoptilolite. In one growth trial, crossbred pigs averaging 25 kg initial body weight were assigned to diets containing no zeolite, .3% zeolite A or .5% clinoptilolite for a 6-wk growing phase trial. Average daily gain (ADG), average...

One of the most attractive properties of zeolites are their well organized nanopores and nanochannels which serve readily as supporting hosts for various molecules. Encapsulation of catalytically active transition metal complexes inside the nanopores of zeolites, often referred to as ‘ship-in-a-bottle’ systems,1 has been believed to be one of the most promising strategies in the development of ...

A simple and versatile approach has been developed to synthesize different carbon/zeolite T functional membrane materials. The precursors of the membrane are composed of polyimide matrix and dispersed zeolite T particles. Membranes prepared by pyrolysis at 973 K showed excellent gas (H2, CO2, O2, N2, CH4) permeability and selectivity and the gas selectivity (O2/N2, CO2/CH4) of the functional me...

Novel nanocomposites consisting of a water-soluble acrylamide-based photopolymer and colloidal zeolite nanoparticles of zeolite Beta and zeolite A were prepared. The interactions between the photopolymer components and zeolite nanoparticles in the photopolymerizable nanocomposites were characterized for the first time by (13)C nuclear magnetic resonance and visible spectroscopy. It was found th...

UNLABELLED The influence of natural zeolite on biogenic amines (BAs) and ammonia (AMN) production by eight common gram negative and positive foodborne pathogens (FBP) were investigated in histidine decarboxylase broth (HDB). Presence of 1% zeolite in the HDB resulted in significantly higher AMN production. Histamine (HIS) production by gram positive bacteria was as low as 0.5 mg/L, whereas Esch...

This article reported a novel low-temperature process for aromatics production through lignin depolymerization catalyzed by 0.1 wt% Pd-zeolite Y catalyst prepared by a facile method. Under the same reactive condition, the as-prepared Pd-zeolite Y catalysts exhibited much higher catalytic efficiency than zeolite Y or commercial Pd/Al2O3–zeolite composites. The selectivity of the Pd-zeolite Y tow...

We report the quantitative, non-destructive determination of the concentration profile of an organic molecule in a nanoporous polycrystalline zeolite molecular sieve membrane, by step scan infra-red photoacoustic experiments and analysis. An important application of stepscan photoacoustic spectroscopy is the transport-model-independent experimental description of membrane transport, by simultan...
