Polyoxometalates (POMs) as metal-oxide anions have exceptional properties like high negative charges, remarkable redox abilities, unique ligand properties and availability of organic grafting. Moreover, the amenability of POMs to modification with different materials makes them suitable as precursors to further obtain new composites. Due to their unique attributes, POMs and their composites have been utilized as adsorbents, electrodes and catalysts in extraction, and electrochemical and optical detection methods, respectively. A survey of the recent progress and developments of POM-based materials in these methods is therefore desirable, and should be of great interest. In this review article, POM-based materials, their properties as well as their identification methods, and analytical applications as adsorbents, electrodes and catalysts, and corresponding mechanisms of action, where relevant, are reviewed. Some current issues of the utilization of these materials and their future prospects in analytical chemistry are discussed.
多金属氧酸盐（POMs）作为金属氧化物阴离子具有独特的性质，如高负电荷、显著的氧化还原能力、独特的配体性质和有机接枝的可用性。此外，POMs 易于与不同材料进行修饰，这使它们适合作为前体进一步获得新的复合材料。由于其独特的属性，POMs 及其复合材料已分别作为吸附剂、电极和催化剂用于萃取以及电化学和光学检测方法中。因此，期望对基于 POM 的材料在这些方法中的最新进展和发展进行综述，这将非常有趣。在本文综述中，综述了基于 POM 的材料及其特性、鉴定方法以及作为吸附剂、电极和催化剂的分析应用，以及相关的作用机制（在相关情况下）。讨论了这些材料在分析化学中的当前应用问题和未来前景。
