Due to the serious threat of heavy metal oxoanions to human health and the natural environment, their efficient removal from water contaminants has become a vital issue. Currently, adsorptive removal is one of most promising approaches to purify contaminated water. Thus, the exploration of advanced adsorption materials has attracted widespread attention. Metal-organic frameworks (MOFs) with the advantages of tunable porosity, high surface area, and abundant functional groups are superior than conventional adsorbents. Herein, this review summarizes recent progress in different MOFs as outstanding adsorbents to remove heavy metal oxoanions from water, including typical SeO₃²⁻/SeO₄²⁻, HAsO₄²⁻/H₂AsO₄⁻/H₃AsO₃, and CrO₄²⁻/Cr₂O₇²⁻. In addition, their adsorption mechanisms are also involved, which is conducive to not only understand the adsorption process between MOFs and heavy metal oxoanion contaminants but also design new MOFs-based adsorbents with excellent performance for further research.

由于重金属含氧阴离子对人体健康和自然环境的严重威胁，有效去除水中的污染物已成为至关重要的问题。当前，吸附去除是净化污水的最有前途的方法之一。因此，对高级吸附材料的探索引起了广泛的关注。具有可调节的孔隙率，高表面积和丰富的官能团的优点的金属有机骨架（MOF）优于常规吸附剂。在此，本综述总结了不同MOF作为杰出的吸附剂从水中去除重金属氧阴离子的最新进展，这些吸附剂包括典型的SeO ₃ ^2- / SeO ₄ ^2-，HAsO ₄ ^2- / H ₂ AsO。₄ ^- / H ₃ ASO ₃，和的CrO ₄ ^2- / Cr的₂ ö ₇ ^2-。此外，它们的吸附机理也参与其中，这不仅有助于了解MOF和重金属氧阴离子之间的吸附过程，而且有助于设计性能优异的新型基于MOF的吸附剂，以供进一步研究。
