Abstract:Using fly ash to synthesize zeolite molecular sieves can improve the reuse value of coal fly ash resources, reduce the synthesis cost of the zeolites, and protect the ecology. A novel approach was proposed to prepare zeolite socony mobil‐5 (ZSM‐5) zeolite via one‐pot hydrothermal synthesis. The mesoporous ZSM‐5 synthesized by adjusting the molar ratio of chemical reagents has higher crystallinity, larger specific surface area, and more adsorption sites. An analysis of methylene blue (MB) adsorption on mesoporo… Show more
“…This demonstrates that both types of adsorbents can sustain a high dye removal rate even after multiple uses, rendering them cost-effective and environmentally friendly solutions for dye adsorption. 65 …”
Surface enhanced coal fly ash (SECFA) has been prepared using acid–base treatment which showed 97.52% dye removal while raw coal fly ash (RCFA) removed only 81.52% dye from wastewater at given conditions.
