Preparation of hierarchical porous metal-organic framework HKUST-1 and its adsorption removal of SudanⅠ

摘要：

黄河流域作为我国重要的生态屏障和经济带,面临着新污染物的环境治理挑战.针对流域内典型污染物的治理需求,聚焦环境中广泛存在且危害严重的苏丹工污染物的去除,以金属有机骨架 HKUST-1为基质,十二烷基硫酸钠为软模板剂,制备含有微孔-介孔结构的多级孔 HKUST-1材料(HP-HKUST-1).结果显示,HP-HKUST-1中同时含有微孔和介孔结构,对苏丹工的最大吸附容量达149.25 mg*g-1,是相应微孔型HKUST-1的5.69倍,且在90min内达到吸附平衡,该过程符合假二级动力学模型和Langmuir模型,升温有利于吸附过程进行,将HP-HKUST-1作为吸附剂用于实际样品中苏丹I的去除,去除回收率为90.10%~110.50%，且经过5次再生循环后,回收率仍大于87%.该工作为拓展金属有机骨架材料在环境污染物吸附去除领域的应用提供了新的策略.

The Yellow River Basin, as a crtdial ecological barrter and economic zone in China, requires efficient removal of pollutants from its environment to protect both the ecological environment and human health. This study focuses on the high-efficiency removal of SudanⅠ pollutant by synthesizing a hierarchical porous HKUST-1 material(HP-HKUST-1) with miero-mesoporous strtetures, using metal-organic framework HKUST-1as the matrix and sodium dodecyl sulfate as a soft template.The results showed that HP-HKUST-1 simultaneously possesses micropores and mesopores, achieving a maximum adsorption capacity of 149.25 mg.g-1 for SudanⅠ,which was 5.69 times higher than that of microporous HKUST-1. The adsorption process was consistent with the pseudo-second-order kinetic model and Langmuir model ,and the adsorption equilibrium can be reached within 90 min, higher temperature favoring the adsorption process, As an adsorbent, HP-HKUST-1 can remove 90.10%-110,50% of SudanⅠ in real samples, After 5 cycles, the recovery of HP-HKUST-1 for Sudan Ⅰ remains above 87%.This work provides a nove strategy for expanding the application of metal-organic frameworks in the adsorption and removal of environmental pollutants.
