摘要

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.
