The Synthesis of Zeolite Using Fly Ash and its Investigate Adsorption Character

摘要

Zeolite was synthesized from coal fly ash produced by a domestic power plant and applied for the removal of ammonia from waster water.Zeolite was synthesized using a hydrothermal mehtod involving an akaline reaction with NaOH,and adsorpton experiments and simulations were conducted.Adsorption experiments with the pelletized spherical zeolite were carried out.The experimental data obtained from adsorption isotherms agreed well with the Langmuir equation.Also,most of the correlated results for the fixed bed model based on surface diffusion and Sips adsorption isotherms equation were consistent with the experimental data.
