Synthesis of hyper-cross-linked resins with almost all micro/mesopores as well as controllable functional groups is still challenging. Herein we developed a kind of phenol-modified hyper-cross-linked resins with almost all microimesopores, and controlled the uploading amount of phenol on the surface. The results indicated that, due to producing rigid methylene cross-linking bridges, these resins were typical micro/mesoporous materials, and the micropore surface area and micropore volume were up to 70% of the total Brunauer-Emmett-Teller (BET) surface area and pore volume. Moreover, the functionalized polarity of these resins could be accurately controlled by adding different amount of phenol in the reaction. These as-prepared resins were employed as the adsorbents for adsorption using aniline as the adsorbate, and the adsorption experiments showed that these resins were efficient for adsorption of aniline, and the resin adding 5% (w/w) phenol in the reaction possessed the largest equilibrium capacity (qmax =169.2 mg/g). The adsorption was very fast, 40 min was enough for the equilibrium, and the micropore diffusion model described the kinetic data very well. (C) 2016 Elsevier Inc. All rights reserved.
