With cation exchange resin and ferrous chloride as raw material,through ion exchange,carbonization process,the preparation of iron modified carbonized resins as adsorbent.In aqueous solution of norfloxacin adsorption experiment of the preliminary results show that the adsorption quantity of norfloxacin is up to 40.49 mg/g. With the Langmuir and Freundlich equation of adsorption equilibrium data fitting.The effects of experimental parameters such as adsorption time,pH,NOR concentrationand temperature on the adsorption efficiency have been investigated.The adsorption capacity of NOR with iron modified carbonized resin is better under the conditions of adsorption time 3 h, pH 6,NOR concentration 10.0 mg/L,room temperature.The adsorption of NOR with the adsorbent follows the pseudo-second-order kinetics model.The adsorption process is an exothermic one,and the desorption data can be fitted with Freundlich isotherm models.
