The qm obtained for CIP adsorption on CNFs is 10.36 mg/g(31.26 mol/g) (Table 4), which is similar to the qm of CIP adsorption on biocomposite fibers [26]. Considering that the CIP molecule possesses a planar configuration and the approximate dimensionsof 13.5˚A × 3˚A × 7.4˚A, it is possible for CIP molecule to penetrate into the pores of CNFs [32]. On the other hand, the adsorption of CIP on CNFs was carried out in a continuous flowing mode, which is more applicable mode of adsorption for removing the pollutants in practical water treatment. Furthermore, the CNFs are relatively cheap and easily accessible due to the widely commercial production. From this point of view, the dynamic adsorption of pollutants on CNFs is a promising approach in the field of water treatmentengineering.
