ادامه مطلبZeolites have the unique ability to adsorb N 2 more strongly than O 2 (i.e., by a factor of 2 or more in terms of pure component adsorption amounts). The main reason for this is the interaction between the quadruple moment of N 2 and the cation that is attached to the zeolite framework. [15].

ادامه مطلبunder research [3–8]. The suitability of zeolite materials for the capture of CO 2 has been reported by many research groups. Silica and alumina are the major composition of a zeolite material. The porous structure of a zeolite is advan-tageous for its CO 2 adsorption. Generally, zeolites are acidic in nature due to the presence of and ...
ادامه مطلبThe schematic of the zeolite-based composites used for the wastewater treatment from 2011 to 2020 is presented in Fig. 1a. As shown, many researchers attracted to design the novel zeolite-based composites and the reported studies about their application for the uptake of contaminants from water sources have been continuously increased in the last decade.
ادامه مطلبZeolite Pure is the best proven heavy metal detox product on the market. It is a safe natural volcanic mineral that is specifically micronized in powdered form between 0-40 microns. This allows it to enter and detox the entire body through the blood, organs, and the gut where the immune system is located. There are no side effects!
ادامه مطلبThe selective catalytic reduction (SCR) of NO x with NH 3 at high temperature (T > 500 °C) usually has low conversion efficiency due to the undesired NH 3 over-oxidation. To suppress the oxidation of NH 3 to NO x, we proposed a Fe-exchanged zeolite catalyst with the modification of Ni and W for the NH 3-SCR process, which was investigated in a wide temperature range (200–850 °C).
ادامه مطلبbiodegradable substances there is no risk because they are rapidly removed from the environment by biodegradation. (4) SCHER is requested to comment whether the substitution of phosphate-based detergents in the EU by zeolite-based detergents would lead to a significant increase in health or environmental risks.
ادامه مطلبZeolite membranes and films have been employed to modify the surface of conventional chemical electrodes, or to conform different types of zeolite-based physical sensors [58]. In quartz crystal microbalances, zeolites are used to sense ethanol, NO, SO 2 and water. Cantilever-based sensors can also be fabricated with zeolites as humidity sensors.
