Zeolites have become promising adsorbents for wastewater treatment due to their enhanced
adsorption capacity, stability of crystalline structure, high porosity and surface area. One of …

The removal of phosphate from aqueous solution by the adsorption process using zeolite
synthesized from fly ash was investigated in this study. The XRD patterns revealed that the …

Natural zeolite has been regarded as an adsorbent for cation removal in water. However,
natural zeolite cannot effectively adsorb anions due to the negative charge. In recent years …

Zeolite-A was synthesized from kaolin activated at 500° C at relatively lower temperature
than the studies reported in the literature. The metakaolin formed at 500° C was used to …

Removal of phosphate ions from aqueous environment has become a global concern.
Adsorption is one of the most efficient methods for removal of various pollutants. In this …

In this study, zeolites (FA6, FA12, and FA24) were prepared from JIS Type-II fly ash (FA) by
alkaline hydrothermal treatment, and their physicochemical characteristics were …

The optimum parameters for synthesis of zeolite NaA based on metakaolin were
investigated according to results of cation exchange capacity and static water adsorption of …

Coal gasification is a new direction for the clean utilization of coal, but it also brings huge
environmental pressure on solid waste. In this paper, the high-crystallinity single-phase …

The aim of the present study is to investigate the removal of ammonium ions from aqueous
solutions using the natural Western Azerbaijan zeolite by utilizing ion exchange process …

In this paper, the zeolite was synthesized from a combination of oil shale ash and coal fly
ash and was used to remove heavy metals from aqueous solution. The structural …
