Simultaneously capturing organic pollutants and heavy metal can greatly reduce the water remediation time and cost, however it is still a great challenge presently. Herein, two novel thiol/methylthio–functionalized porous aromatic frameworks were synthesized as sorbents via the Sonogashira–Hagihara reaction of 1,3,5–triethynylbenzene and 1,3,5–tris(4–bromophenyl) benzene, the subsequent chloromethylation of the phenyl rings, and the final nucleophile substitution of –Cl groups by NaSH/NaSMe. These two sorbents were characterized by FT–IR spectra, energy dispersive X-ray spectra, scanning electron microscope, nitrogen adsorption analysis, thermo–gravimetric analysis, and elemental analyses. Adsorption experiments displayed that new sorbents had high uptake abilities and fast adsorption kinetics for aromatic pollutants and mercury (II) (Hg(II)). The maximum adsorption capacity (Q_max) of toluene and m–xylene on both new sorbents were 531.9–571.4 mg/g with the kinetic binding rate constants (k_obs) of 0.00276–0.02422 g/mg/min, and the Q_max values of Hg(II) were 148.1–180.3 mg/g with k_obs of 0.00592–0.01573 g/mg/min. Moreover, new sorbents indicated high simultaneous uptake abilities for these pollutants with good reusability, and finally they were successfully applied to the simultaneous remediation of these pollutants in two simulated sewages with high and low concentration, indicating their great practical application potential in wastewater remediation.

同时捕获有机污染物和重金属可以大大减少水体修复的时间和成本，但目前仍是一个很大的挑战。在此，通过合成两种新型硫醇/甲硫基功能化多孔芳香骨架作为吸附剂1,3,5-三乙炔苯和1,3,5-三(4-溴苯基)苯的Sonogashira-Hagihara反应，随后苯环的氯甲基化，以及-Cl基团最终被NaSH/NaSMe亲核取代。这两种吸附剂通过 FT-IR 光谱、能量色散 X 射线光谱、扫描电子显微镜、氮吸附分析、热重分析和元素分析进行​​表征。吸附实验表明，新型吸附剂对芳香族污染物和汞（II）（Hg（II））具有高吸附能力和快速吸附动力学。最大吸附量（Q_最大甲苯和的）米二甲苯在两个新吸附剂为531.9-571.4毫克/克与动力学结合速率常数（ķ _OBS) 为 0.00276–0.02422 g/mg/min，Hg(II)的Q_最大值为 148.1–180.3 mg/g，k _obs为 0.00592–0.01573 g/mg/min。此外，新型吸附剂对这些污染物表现出较高的同时吸附能力和良好的重复利用性，最终成功应用于高、低浓度两种模拟污水中这些污染物的同时修复，表明其在废水修复中具有巨大的实际应用潜力。
