Removal of Heavy Metal from Wastewater Using Zeolite from Fly Ash
Abstract:
Coal fly ash (CFA) was modified by hydrothermal treatment using NaOH solutions for zeolite synthesis. The XRD patterns of zeolite and coal fly ash are presented. The synthesized zeolite was investigated for adsorption of heavy metal ions in aqueous solution. It was shown that fly ash and the modified forms could effectively absorb heavy metals. The adsorption isotherm could be described by Freundlich isotherm equations. The pseudo second-order kinetics would be better for fitting the dynamic adsorption of Cu2+ and Cd2+.
