Characterization of X-type Zeolite Prepared from Coal Fly Ash
This study presents experimental results dealing with the possibility of transforming F-class fly ash into a zeolitic material. Two types of synthesis methods were used in the research: hydrothermal and low-temperature synthesis. As a result of alkaline reaction of fly ash with NaOH, all experimental cases yielded zeolitic material that are rich in a Na-X phase. The mineralogical composition (d...
متن کاملZeolite Synthesis Strategies from Coal Fly Ash: A Comprehensive Review of Literature
The ever increasing energy demand in developing world will result in sustainable increase in the fly ash generation, which will remain a cause of concern as far as its management is concerned. However, technological advance may prove to be effective in fly ash management as well as its possible utilization through the zeolites. The zeolites are known to possess many beneficial properties (such ...
متن کاملAdsorption of Cu(II) from Aqueous Solution on Fly Ash Based Linde F (K) Zeolite
The work focuses on the removing of Cu(II) from aqueous solution by Linde F(K) zeolite. The zeolite is synthesized from fly ash by hydrothermal process. The adsorption experiments discuss several factors including the optimal solution pH, zeolite dosage, adsorption temperature, adsorption kinetics and adsorption isotherm equation. The results show that, the optima...
متن کاملAdsorption of anionic dyes from aqueous solution on zeolite from fly ash-iron oxide magnetic nanocomposite
Magnetic zeolite/iron oxide nanocomposite was prepared by mixing zeolite synthesized from coal fly ashes with magnetite nanoparticles in suspension and was used for the removal of Reactive Orange 16 (RO16) and Indigo Carmine (IC) from aqueous solutions. The effect of various experimental parameters such as contact time, pH, adsorbent dose and temperature were investigated. The experimental data...
متن کاملAdsorption of tungsten onto zeolite fly ash produced by hydrothermally treating fly ash in alkaline solution.
Fly ash (FA) was hydrothermally treated in an alkaline solution to produce zeolite fly ash (Z-FA). The properties of the FA and Z-FA were investigated. The amounts of tungsten (W) adsorbed onto the FA and Z-FA surfaces were evaluated. Z-FA was produced by hydrothermally treating FA in an alkaline solution. The specific surface area and pore volume of the Z-FA were greater than those of the FA. ...
