Abstract：Polystyrene-divinyl benzene resin NDA-150 was prepared, and its static and dynamic adsorption properties of NDA-150 resin toward phenol and 2-naphthol were compared with commercially available XAD-4 resin. Taking the properties of adsorption resins and phenolics into account, the differences of adsorption capacities resulted from the specific surface area and micropore volume of adsorbents and Kow value of phenolics. Dynamic experimental data showed that breakthrough time and saturation time of the resin advanced with the increase of velocity, while saturating adsorption capacity decreased, but with the increase of initial concentration, breakthrough time and saturation time of the resin advanced, and equilibrium adsorption capacity increased. The dynamic experimental data of NDA-150 resin on adsorption of phenol and 2-naphthol accorded well with Thomas and LDF models. The ethanol solution of 60% mass fraction dissolved with 0.1 mol/L NaOH had a desorption rate of over 90% for 2-naphthol and phenol.
