In this work, zeolite based on coal fly ash was firstly synthesized via wet milling for the adsorption of lead (Pb(II)). The effects of contact time, solid-to-liquid ratio and initial pH of solution on Pb(II) removal were investigated in detail. The experimental data showed that synthesized zeolite has high adsorption capacity of 99.082 mg of …

This partly resulted in the exclusion of CFB fly ash from the scope of the general standard specifications for pulverized coal fly ash (PCFA) for use in concrete [5,18,19,20]. Co-combustion of coal with alternative fuel, such as waste-derived fuel, is a relatively new development for industrial boilers.

The dispersion of fly ash in water results in an alkaline pH from 10 to 13. At high pH, the fly ash becomes negatively charged allowing the removal of heavy metal ions by precipitation and electrostatic adsorption from water (Cho et al., 2005). Fly ash can be modified or transformed into new materials for heavy metal ions adsorption.
