Abstract：Three types of aminatedhypercrosslinked polymeric adsorbents were successfully prepared. The static adsorption and thermodynamics of the adsorption for phenol and aniline onto the homemade adsorbents from aqueous solution were investigated. The results show that the adsorption capacities of phenol and aniline are both decreased with the increasing of amido content, while the decreased rate of aniline is bigger than that of phenol. The correlation coefficients are all over 099, which shows that both Langmuir and Freundlich models can well illuminate the adsorption process. The adsorption of phenol is pushed by physical and chemical interaction, while the adsorption of aniline is mainly pushed by physical interaction. Indexes of n in Freundlich regression equations are all over 1, which means that the adsorptions for both phenol and aniline are favorable adsorption. Thermodynamics data indicate that the adsorptions of phenol and aniline are exothermic and spontaneous process. The absolute value of adsorption entropy change increases with the increasing of amido content, which means that strong interaction between adsorbate and adsorbent is formed by amido.
