摘要

全球每年向自然环境排放的毒性第三大的离子汞(Hg)高达1万吨,对公众健康构成重大威胁。然而,具有柔性吸附位点的传统吸附剂对汞的去除能力有限,特别是在高酸性和多种竞争离子环境中。本文选择Hg(II)离子配位的3,3 ',5,5 ' -四溴-2,2 ' -双噻吩作为构建单体,通过Suzuki偶联反应构建多孔芳香骨架(PAF)。根据汞离子的配位结构,两个噻吩片段的位置和角度由四重共价键固定。这些共价结合的双噻吩单元对Hg(II)离子的结合亲和力提高了约303%,对Hg(II)离子的选择性提高了约140.0倍。此外,所得固体(MILNU-49)在5000.0 ~ 2.0 ppb范围内具有较好的去除率,在5 h内对Hg(II)实际酸性废水的去除率达到99.96%以上。值得注意的是,MILNU-49在酸性条件下对汞离子的吸附优于先前报道的吸附剂。这项工作列举了一种设计选择性和高亲和力结合位点的策略,这在环境,检测和能量存储领域具有很大的兴趣。

Global release of up to 10 000 tons per year of mercury (Hg), the third most toxic ion, into the natural environment poses a significant threat to public health. However, conventional adsorbents with flexible adsorption sites have limited capability in mercury removal, especially in highly acidic and multiple competing ion environments. Herein, Hg(II) ion coordinated 3,3′,5,5′-tetrabromo-2,2′-bithiophene is selected as the building monomer to construct the porous aromatic framework (PAF) through a Suzuki coupling reaction. The positions and angles of the two thiophene fragments are fixed by quadruple covalent bonds according to the coordination structure of the mercury ion. These covalently bounded bithiophene units exhibited ≈303% increased binding affinity and ≈140.0-fold enhanced selectivity for Hg(II) ions, compared with flexible bithiophene moieties. In addition, the resulting solid (MILNU-49) illustrates outstanding removal capability with a concentration varying from 5000.0 to 2.0 ppb, correspondingly, the removal efficiency is over 99.96% within 5 h from Hg(II) actual acidic wastewater. Remarkably, MILNU-49 outperforms previously reported adsorbents for the adsorption of mercury ions under acidic conditions. The work enumerates a strategy for designing selective and high-affinity binding sites, which are of great interest in the fields of environment, detection, and energy storage.
