【摘要】：金属纳米材料因其大量生产和广泛使用而不可避免地会释放到环境中,给生态环境和人体健康造成潜在的负面影响.发展环境样品中金属纳米材料高效灵敏的分析测定方法,对于研究其在环境中的分布、转化、归趋、效应和生物安全性具有重要意义.研究表明,金属纳米材料组成、结构、形态和粒径分布等显著影响其环境过程和生物效应.因此,与传统的污染物分析不同,金属纳米材料分析不仅需要测定其化学组成和浓度,还需表征其粒径、形貌和表面电荷等.本文综述了近十年来关于环境中金属纳米材料的分离及测定的相关手段和方法,主要包括痕量金属纳米颗粒的萃取富集方法以及不同粒径纳米颗粒和相应金属离子的分离方法,并展望了发展前景.
[Abstract]:Metal nanomaterials will inevitably be released into the environment due to their mass production and extensive use, resulting in potential negative effects on the ecological environment and human health. The development of highly efficient and sensitive analytical methods for the determination of metal nanomaterials in environmental samples is of great significance for the study of their distribution, transformation, fate, effect and biosafety in the environment. The results show that the composition, structure, morphology and particle size distribution of metal nanomaterials significantly affect their environmental processes and biological effects. Therefore, different from the traditional analysis of pollutants, the analysis of metal nanomaterials needs not only the determination of their chemical composition and concentration, but also the characterization of their particle size, morphology and surface charge. In this paper, the methods and methods related to the separation and determination of metal nanomaterials in the environment in recent ten years are reviewed, including the extraction and enrichment of trace metal nanoparticles and the separation methods of different particle sizes and corresponding metal ions. The prospect of development is also prospected.
