| Abstract: | Zeolite was synthesized with fly ash. The synthesized and optimization conditions of adsorbing sulphate by the synthesized zeolite with fly ash were researched by the single factor experiment and the orthogonal design. The re- sults showed that the optimum processing parameters was dissolving NaOH to fly ash mass ratio 1, melting temperature 400℃, melting time lh, hydrothermal temperature 60℃ and hydrothermal time 4h. The main and secondary factors and level effeeting sulfate removal rate were zeolite size 80 mesh, stirring time 45min, zeolite dosage 10g·L^-1 and solution pH value 5. |
