Poultry operations are associated with emissions of aerial ammonia (NH3), volatile organic compounds (VOCs), and odor, and the magnitude of emissions is influenced by manure management practices. As a manure treatment additive, zeolites have been shown to have the potential to control NH3. Because of their properties it is also expected that zeolites could effectively adsorb VOCs and odor. The ...

A detailed and systematic polarized confocal fluorescence microscopy investigation is presented on three batches of large coffin-shaped ZSM-5 crystals (i.e., parent, steamed at 500 °C, and steamed at 700 °C). In total, six laser lines of different wavelength in the visible region are employed on two crystal positions and three orientations with respect to the polarization plane of the excitatio...

This study delineates a simple and versatile approach for the removal of nitrogen monoxide (NO) and volatile organic vapors over composites of titanium dioxide (TiO2) catalyst/zeolite adsorbent under ultraviolet (UV) irradiation at ambient temperature. The catalytic adsorbents with different TiO2/H-ZSM-5 zeolite ratios were prepared by a simple insipient wetness impregnation method. It was foun...

In recent years, natural substances such as zeolite have been used to absorb heavy metals in soil in an attempt to decrease their availability to plants. Compared to other techniques, the use of zeolite is fast, clean, and inexpensive. This research was carried out to investigate the effects of an Iranian natural zeolite (clinoptilolite) on stabilizing Cd-contaminated soil treated with 0.01 M C...

Two experiments were conducted to investigate the effects of sodium sulfate water and the efficacy of nonnutritive feed additives in nursery pig diets. In Exp. 1, 320 barrows (5.4 ± 0.1 kg BW and 21 d of age) were allotted to 1 of 8 treatments for 24 d in a 2 × 4 factorial with 2 levels of sodium sulfate water (control or 3,000 mg sodium sulfate/L added), and 4 dietary zeolite (clinoptilolite) ...

Abstract This work aimed at treating OMW by developing an environmentally friendly and cost-effective media capable of removing phenolic compounds upon the interaction between magnetic nanoparticles sorbent material such as zeolite. Magnetite (Fe 3 O 4 ) goethite (FeO(OH)) were prepared using microemulsion method dimethylene-1,2-bis (dodecyl dimethyl ammonium bromide) (CTAB) a surfactant. The h...

The structure and reactivity of a room temperature stable zinc carbonyl complex in Zn-modified H-ZSM-5 zeolite were revealed by solid-state NMR spectroscopy.

One way to reduce phosphate levels in water is by adsorption. Adsorption considered as the best wastewater treatment method because main material, namely adsorbent, abundant and easy use. This research was conducted determine ability of zeolite combined with bentonite adsorb water, optimum time, pattern adsorption isotherms capacity. The studies included characterization adsorbent well its appl...

the purpose of this study is comparison of manganese absorption capacity by natural and modified zeolite. for this purpose used by from semnan mines zeolite with mean particle diameter of 360 micrometer. for modified zeolite, 5 g amount of natural zeolite with 100 ml of 1 m sodium chloride solution mixed and maintained at 24 hours in room temperature. for measure specific surface of absorbents,...

Zeolite-based catalyst bodies are commonly employed in a range of important industrial processes. Depending on the binder and shaping method chosen, vast differences in the reactivity, selectivity and stability are obtained. Here, three highly complementary micro-spectroscopic techniques were employed to study zeolite ZSM-5-binder interactions in SiO2-, Al2O3-, SiO2 : Al2O3- (2 : 1 mix) and kao...
