摘要：
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 methylene blue (MB) in aqueous solution. It was shown that fly ash and the modified forms could effectively absorb MB. The adsorption isotherm could be described by Freundlich isotherm equations. The pseudo second-order kinetics would be better for fitting the dynamic adsorption of MB.
