چکیده مقاله:

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 optimal solution pH is 6 and the efficient zeolite dosage is 4g/L. Higher reaction temperature could favor the removal of Cu(II). The adsorption of Cu(II) on Linde F (K) zeolite is monolayer adsorption. The experiment data could be calculated by pseudo-second-order model and Langmuir isotherm. The adsorption process is endothermic and spontaneous and the system disorder increases with temperature.

Adsorption 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. ...

Formation of linde F zeolite by KOH treatment of coal fly ash

Zeolitic products formed by hydrothermal treatment of coal fly ash (FA) with KOH aqueous solution under various reaction conditions were examined. Only linde F-type zeolite (K2Al2Si2O8·3H2O) was newly formed at atmospheric pressure, except formation of a small amount of kalsilite (KAlSiO4) at longer reaction time. The yield of the linde F zeolite was highest when reaction time, temperature, KOH...
