Progress of air sampling theory for gas-phase SVOCs based on polymer materials as sorbent

This article reviews the development of mathematical modeling theories for atmospheric samplers based on polymer materials as sorbent in the quantitative collection of semi-volatile organic compounds (SVOCs). It presents three core modelling theory for air sampling: the front chromatography theory for active air sampler (AAS), the dual-film theory for passive air sampler (PAS), and the dynamic theory for PAS. Additionally, it looks ahead to future research trends and theoretical expansion directions related to these technologies.
