| 摘要: |
| 对改型沸石除氟过程的吸附模式、动力学机制和吸附热力学性质进行了研究，结果表明，改型沸石除氟过程的吸附是按Freundlich吸附模式进行的，Freundlich方程能够良好地关联氟离子在改型沸石上的吸附平衡；改型沸石具有较强的脱氟能力，其吸附速率是内扩散控制；改型沸石脱氟过程为放热的化学吸附过程，温度升高对脱氟不利。 |

| A study on the defluoridation thermodynamic and kinetics of the version zeolite |
|
|
| Abstract: |
| Adsorption model,dynamic mechanism and adsorption thermodynamic property of the version zeolite are discussed.The study results show that,Freundlich equation can favorably associate fluorine ion adsorption equilibrium in the version zeolite,and the adsorption model is Freundlich model.Adsorption process is internal diffusion control,defluoridation material has good defluoridation capability,adsorption process is exothermal chemical adsorption,and rising temperature is not good to adsorption. |
| Key words: version zeolite defluoridation material adsorption model kineties mechanism thermodynamic property |
