Three amino-modified hyper-cross-linked resins (HCP-M, HCP-E, and HCP-D) were synthesized, and they were evaluated for adsorption of p-chlorophenol from aqueous solution. The results indicated that the uploading amounts of the amino groups on the three resins followed an order of HCP-M < HCP-E < HCP-D, while their Brunauer-Emmett-Teller surface area had an opposite order. The three resins were efficient for adsorption of p-chlorophenol from aqueous solution and hydrogen bonding was the main driving force for the adsorption. The isosteric adsorption enthalpy at zero fractional loading had an order of HCP-M (-44.92 kJ/mol) < HCP-E (-57.12 kJ/mol) < HCP-D (-61.53 kJ/mol). At the initial concentration of 502.1 mg/L and the flow rate of 68 mL/h, the saturated dynamic capacities of HCP-M, HCP-E, and HCP-D were 388.1, 394.3, and 318.1 mg/g dry resin, respectively, and these resins could be completely regenerated and repeatedly used.
