- Abstract:
- Nanoparticles are widely applied owing to their special physical and chemical properties. They can enter the aquatic environment through various ways, causing potential risks to the aquatic ecological environment and human health. Characterization and detection of nanoparticles is the key and basis for exploring their occurrence, migration, transformation and eco-toxicological effects in aquatic environment. Metal (oxide) nanoparticles exist in the aquatic environment in trace form and undergo a series of physical and chemical changes such as adsorption, agglomeration, sedimentation, dissolution and transformation, and the presence of different forms of metal ions also affects the particle size detection results of nanoparticles. Therefore, extraction and enrichment, separation and characterization of metal (oxide) nanoparticles in aquatic environment have become a hot research topic. This paper summarized and compared the common concentration, separation and characterization methods of metal (oxide) nanoparticles in recent years, and prospected the future development and research direction.
