This review presents a comprehensive update on the state-of-the-art of nanometer-sized materials in solid-phase extraction (SPE) of trace elements followed by atomic-spectrometry detection. Zero-dimensional nanomaterials (fullerene), one-dimensional nanomaterials (carbon nanotubes, inorganic nanotubes, and nanowires), two-dimensional nanomaterials (nanofibers), and three-dimensional nanomaterials (nanoparticles, mesoporous nanoparticles, magnetic nanoparticles, and dendrimers) for SPE are discussed, with their application for trace-element analysis and their speciation in different matrices. A variety of other novel SPE sorbents, including restricted-access sorbents, ion-imprinted polymers, and metal-organic frameworks, are also discussed, although their applications in trace-element analysis are relatively scarce so far.
本综述全面更新了纳米材料在痕量元素固相萃取（SPE）及后续原子光谱检测方面的最新进展。讨论了用于SPE的零维纳米材料（富勒烯）、一维纳米材料（碳纳米管、无机纳米管和纳米线）、二维纳米材料（纳米纤维）和三维纳米材料（纳米颗粒、介孔纳米颗粒、磁性纳米颗粒和树枝状大分子），及其在不同基质中痕量元素分析及其形态分析中的应用。还讨论了包括受限进样吸附剂、离子印迹聚合物和金属有机框架在内的各种其他新型SPE吸附剂，尽管它们在痕量元素分析中的应用目前相对较少。
