In this paper,the adsorption behaviors of phenol on polymeric adsorbents(Amberlite XAD4,NDA101,and D301) were investigated in batch system at 293,303,and 313 K,respectively.As the results shown,the adsorption isotherms of phenol on all adsorbents can be well fitted by Langmuir and Freundlich equations,which indicate a favorable and exothermic process.The adsorption capacity on a newly developed aminated adsorbent,NDA101,on which adsorption could be achieved by both hydrogen bonding interaction and π-π interaction,are higher than that on a weak base adsorbent,D301,on which adsorption could be achieved by hydrogen bonding interaction only,and on a nonpolar adsorbent,XAD4,on which adsorption could be achieved by π-π interaction only.The results of this paper indicate that the synergistic effect of some weak interactions,which occur simultaneously would contribute more to the adsorption than that occur individually.
