摘要：Removing phenolic compounds from water resources is urgent as they have seriously damaged aquatic ecological equilibrium. In this study, divanillin-based porous organic polymers (DPP) and 2,5-furandicarboxaldehyde-based porous organic polymers (FPP) were prepared from sustainable lignocellulose-derivatized monomers using a onestep synthetic method. The characterization highlighted the large Brunauer-Emmett-Teller (BET) surface area (SBET 513.9 and 772.8 m2 center dot g- 1), mainly mesoporous property (3.4 and 6.5 nm) and high nitrogen content (over 25%) of the obtained DPP and FPP, which rendered them high adsorption affinity toward phenolic pollutants. Specifically, DPP and FPP exhibited the highest adsorption capacity for p-nitrophenol (PNP) (254.2 and 339.4 mg center dot g- 1) calculated by the Langmuir isotherm model. The porous networks of DPP and FPP enabled fast sorption kinetics for PNP with adsorption equilibrium times of only 8 and 4 min, respectively. Thermodynamic investigation revealed adsorption followed spontaneous and exothermic chemisorption processes. The interaction between the PNP and DPP/FPP mainly involved the synergism of hydrogen-bonding interactions, electrostatic force, and 7C-7C stacking interactions. Furthermore, DPP and FPP exhibited outstanding durability and retained over 78.9% and 81.9% removal efficiency for PNP after ten cycles. Therefore, these biobased materials with high adsorption capacity and rapid adsorption rate show promising application in wastewater treatment.
