- 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.
