Abstract:
In view of the problems of
low pre-screening efficiency, a weak Raman signal, and strong fluorescence interference in the
detection of microplastics by traditional Raman spectroscopy, a set of rapid detection system and research methods for microplastics,
including fluorescence imaging technology, differential Raman spectroscopy technology, and confocal microscopic Raman technology,
are constructed in this paper. A 784/785 nm dual-wavelength laser was used as the excitation light source in the rapid detection
system for microplastics. The sediment in the coastal waters of Qingdao Shilaoren was taken as the research object. Polycarbonate and
high-density polyethylene with a particle size of 40 µm in the samples were accurately detected and analyzed. The research
method for microplastics proposed in this study breaks through relevant key technologies, which we believe will help promote the
development of microplastic monitoring technology in the global marine environment and provide strong technical support for the healthy
development of the global marine ecological environment.
