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...

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...

The reaction of fly ash with a KOH solution was used to synthesize Linde F(K) zeolite, following which Fourier transform infrared spectroscopy were used to characterize the crystalline material. The competitive adsorption of Cu, Ni, Pb, and Cd onto this zeolite was subsequently studied in quaternary solution systems. The results show that the metal removal rates gradually increase with incr...
