Coal fly ash: an emerging material for water remediation

Abstract Coal fly ash (CFA) is a byproduct of thermal power plant and collected from flue gases by separator. Composition CFA depends on the type coal used it has both crystalline amorphous character. It considered to be an environmental pollutant in number areas. useful material widely cement production as promising adsorbent for water remediation. remediation wastewater solves problems related quality issues waste management. The physical properties such porosity, surface area, morphology, chemical composition (iron oxide, alumina, silica, titania, etc.) make efficient treatment. also converted geopolymer, which photocatalyst. Dye, organic compounds, toxic heavy metal ions, etc. have been removed using modified adsorbents. Different adsorption efficiencies reported different adsorbate Numbers isotherm kinetic models discussed.
