Abstract：A novel hypercrosslinked polymeric adsorbent modified by methoy and amine (HPAMMA) was successfully prepared. The static adsorption behaviors of aniline and benzene onto HPAMMA in aqueous solution were investigated, and the effects of bifunctional groups on adsorption behavior were discussed. The results show that the adsorption capacity of aniline is significantly bigger than that of benzene under the same conditions. The adsorption of aniline is pushed by physical and chemical interactions, while the adsorption of benzene is mainly pushed by physical interaction. Comparing the adsorption capacity, the resin modified by bifunctional groups is bigger than that modified by one functional group with the assistance of hydrogen bonding. Langmuir models can well illuminate the adsorption of aniline, while the adsorption isotherms of aniline and benzene onto HPAMMA are both conformed to Freundlich models. The correlation coefficients are all over 0.98, and the indexes of n in Freundlich regression equations are all over 1, which means that the adsorptions of aniline and benzene are favorable adsorption. With the increasing of initial adsorbate concentration, the adsorption selectivity is decreased with latter constant value, and it is deceased with the increasing of temperature.
