Research Progress on Analysis Methods of Microplastics in Water

In the environmental water, microplastics is a new pollutant with potential risks because of its strong adsorption and migration ability and bioaccumulation. Because the water environment is complex and the microplastics particles are usually very small, the analysis and identification is the bottleneck of the current research work. Through literature collection and induction, this paper introduces the methods of sample collection, classification and extraction, component identification and analysis of microplastics in water in recent years, and systematically expounds the application and prospect of micro-FTIR in microplastics analysis. By analyzing the applicability and limitations of various methods, the whole process analysis method suitable for microplastics analysis of water environment is summarized, which provides a basis for future research on the occurrence characteristics, migration and transformation laws and potential environmental risks of microplastics in environmental waters.
