Adsorption of phenol onto four hyper-cross-linked polymeric adsorbents: Effect of hydrogen bonding receptor in micropores on adsorption capacity

Phenol was selected as a hydrogen bonding donator to estimate the effect of hydrogen bonding receptor in the micropores of four kinds of different functional group modified hyper-cross-linked adsorbents on adsorption. The adsorption capacity of phenol onto the adsorbents followed the order GQ-1 > GQ-2 > GQ-5 > H103. Density functional theory indicated that hydrogen bonding receptor in the micropores of adsorbent was a crucial factor for the capacity order.164
