Abstract
Atmospheric particulate matter has complex components and a wide range of sources. It not only frequently occurs in bad weather such as haze, but also aggravates environmental pollution as a carrier of pollutants, posing a potential threat to human health. In order to identify its composition characteristics and sort particles with different particle sizes, this study designed a particle sorting structure based on microfluidic technology, in order to provide scientific guidance for solving the problem of atmospheric particulate matter pollution. Based on the principle of microfluidic particle optical sorting, a particle sorting structure of microfluidic technology was designed to achieve continuous sorting of particles with different particle sizes. The results show that the use of optical radiation force and fluid resistance can effectively achieve the separation of particles with different particle sizes, so as to effectively sort the atmospheric particles according to the particle size.
