Covalent organic framework-based DGT sampler for in situ monitoring of per- and polyfluoroalkyl substances in aquatic environments.
Diffusive gradients in thin-films (DGT) is an important alternative to grab sampling for in situ monitoring of emerging contaminants such as per- and polyfluoroalkyl substances (PFAS) in aquatic environments. In this study, a covalent organic framework (COF) was developed as a high-capacity binding material for DGT. Th...
