Research on Rapid Detection of Microplastics in Flowing Water Based on Raman Spectroscopy
Abstract
The widespread use of plastic products has resulted in the pervasive presence of microplastics in both marine and freshwater environments, posing significant risks to aquatic ecosystems. Accordingly, the development of accurate and rapid detection methods for microplastics is an urgent priority. Conventional techniques are often time-consuming and require complex sample preparation. To overcome these limitations, we propose a micro-Raman spectroscopy-based method for the detection and identification of microplastics in flowing water, which eliminates complex sample pretreatment and substantially reduces analysis time. The minimum detectable particle size was 26 μm. Unlike conventional approaches, this method simultaneously acquires particle size and Raman spectral information, enabling rapid detection without complex sample preparation. The approach shows potential for real-time monitoring of microplastics in flowing tap water and marine environments.
