A post-crosslinked polymeric adsorbent was prepared by Friedel-Crafts reaction of the pendant vinyl groups.It was obvious that both the specific surface area and the pore volume of starting copolymers increased significantly after post-crosslinking.Nitrogen adsorption/desorption isotherms and pore size distribution curves revealed that the new pores of the resulted copolymers formed by post-crosslinking reaction were mainly micropores.The results of static adsorption indicated that the adsorbents sorption capability of phenol had been greatly improved after post-crosslinked

while this phenomenon was not obvious to VB12. It could be attributed to the molecular size of VB12

which prevented VB12 diffusing from solution phase into the micropore region formed by post-crosslinking.PDT-55pc exhibited higher adsorption capacity of phenol than the commercial macroporous resin XAD-4 The adsorption capacity of VB12 onto adsorbent PDT-55(polydivinylbenzene

toluene as porogen)，PDT-55pc(post_crosslinking of PDT-55)，PDH-55(polydivinylbenzene

heptane and toluene as porogen)，PDH-55pc(post-crosslinking of PDH-55) was larger than that onto XAD-4.The equilibrium adsorption curves for resins adsorbed phenol and VB12 showed good agreement with the Langmuir and Freundlich isotherm equations.Correlation coefficients were larger than 0.99. Adsorption kinetic curves indicated that the time for adsorption equilibrium of phenol was shorter than that of VB12. The kinetic data were then fitted to the pseudo-first order and pseudo-second order models.The results showed that phenol uptake onto adsorbents could be followed by the pseudo-second order model

while VB12 onto adsorbents would be more suitably represented by the pseudo-first order model.
