摘要:
利用碱改性粉煤灰吸附脱除水中诺氟沙星,采用平衡法测定了改性粉煤灰的平衡吸附量并用Freundlich模型进行了关联,计算了模型参数以及△G、△H和△S等热力学参数.结果表明,改性粉煤灰的比表面积为改性前的3.24倍;实验数据能较好地服从Freundlich模型;改性粉煤灰对水中诺氟沙星的吸附为自发、放热的熵减过程.
Abstract:
The equilibrium adsorption capacity of modified fly ash was determined by equilibrium method and correlated with Freundlich model, and the model parameters and thermodynamic parameters such as △G, △H and △S were calculated. The results showed that the specific surface area of modified fly ash was 3.24 times that of the modified fly ash before modification. The experimental data can better follow the Freundlich model; The adsorption of norfloxacin in water by modified fly ash is a spontaneous, exothermic entropy reduction process.
