摘　　要：三蝶烯和2,4-二氨基-6-苯基-1,3,5-三嗪单体在三氯化铁催化剂作用下,通过一步傅克烷基化(Friedel-Crafts)反应合成了一种新型三蝶烯基超交联多孔共聚物(N-HPC)。采用FT-IR、TEM和SEM等分析方法对获得的材料进行了表征。结果表明,N-HPC具有粗糙不规则的形态、丰富的孔结构以及良好的热稳定性。N-HPC对MG吸附180 min可达到平衡,对MG的最大吸附量(qmax)为150 mg/g,最佳吸附pH值为8.2。同时,N-HPC还具有良好的重复利用性,经过5次吸附解吸循环实验,N-HPC对孔雀石绿的去除率仍可达到70%以上。因此,N-HPC可作为一种理想、高效、易制备、可循环利用的染料废水处理新材料。In the presence of iron trichloride catalyst,the monomeric tricopterene and 2,4-diamino-6-phenyl-1,3,5-triazine were copolymerized and woven into a novel tricopterene-based supercross linked porous copolymer(N-HPC)by a one-step Friedel-Crafts reaction.The obtained material was characterized using a series of analytical methods,which showed that N-HPC has a rough and irregular morphology,an abundant pore structure and stable thermal properties.The adsorption of MG by N-HPC reached equilibrium after 180 minutes.The maximum adsorption capacity(qmax)of N-HPC on MG was 150 mg/g and the optimum adsorption pH was 8.2.Experimentally,the removal rate of malachite green by N-HPC can still reach more than 70%.Therefore,N-HPC can be used as an ideal,efficient,easy to prepare and recyclable new material for dye wastewater treatment.
