Abstract
Materials for binding per- and polyfluoroalkyl substances (PFAS) are disclosed. A fluidic device comprising the materials for detection and quantification of PFAS in a sample is disclosed. The fluidic device may be configured for multiplexed analyses. Also disclosed are methods for sorbing and remediating PFAS in a sample. The sample may be groundwater containing, or suspected of containing, one or more PFAS.
Claims20
A method, comprising:
- capturing a per- or polyfluoroalkyl substance (PFAS) from a sample by
- combining the sample with a composite sorbent, thereby sorbing the PFAS to the composite sorbent to form a PFAS-sorbent, the composite sorbent comprising at least two different materials, (a) and (b), wherein (a) is a metal-organic framework (MOF), a covalent organic framework (COF), a covalent organic polymer (COP), a zeolite, mesoporous silica, or hierarchical porous carbon, and (b) is at least one of a polymer, a zeolite, a covalent organic framework, mesoporous silica, a hierarchical porous carbon, a photocatalyst, a carbon nanotube, graphite, graphene, graphene oxide, a Prussian blue analog, or a metal oxide, wherein
- (i) the MOF, if present, does not comprise [Zr6O4 (OH)4] and 1,4-benzodicarboxylic acid (UiO-66), and/or
- (ii) the polymer, if present, is not poly(ethylene-co-vinyl acetate).
