Enhanced Removal of Phenol by a Hyper-Cross-Linked Resin Functionalized with Composite Properties of Chemical Materials

A hyper-cross-linked polymeric adsorbent GQ-1 functionalized with acetamino groups and hydroxyl groups was synthesized to remove phenol. Results showed that the maximum adsorption capacity of GQ-1 emerged at the molecular state of phenol. More favorable adsorption of phenol onto GQ-1 than XAD-4 was further demonstrated by thermodynamic analysis. The breakthrough capacity of GQ-1 was 2.53 times that of XAD-4 when the effluent concentration reached 5mg/L.
