The development of functionalized hyper-cross-linked resins (HCLRs) with high Brunauer-Emmett-Teller (BET) surface area (S) is of great importance. Herein, a kind of anisole-modified HCLRs was fabricated by two successive Friedel-Crafts reactions and it was used for the adsorption of aniline from aqueous solution. The resultant HCLRs owned high S and plentiful oxygen (O), with the values of 650 m/g and 7.6 wt% respectively. The adsorption experiments indicated that the adsorption of aniline on the prepared HCLRs was efficient with the maximum capacity of 200.6 mg/g at 308 K, and both of the S and the introduced O were beneficial for the adsorption. Additionally, the as-prepared HCLRs had a good reusability without obvious capacity loss after five adsorption-desorption cycles.
具有高比表面积（S）的功能化超交联树脂（HCLR）的开发具有重要意义。在此，通过两次连续的傅-克反应制备了一种苯甲醚改性的 HCLR，用于从水溶液中吸附苯胺。所得 HCLR 具有高 S 和丰富的氧（O），分别为 650 m/g 和 7.6 wt%。吸附实验表明，在 308 K 时，制备的 HCLR 对苯胺的吸附效率很高，最大吸附量为 200.6 mg/g，S 和引入的 O 都有利于吸附。此外，在经过五次吸附-解吸循环后，制备的 HCLR 具有良好的可重复使用性，没有明显的容量损失。
