Cof aerogel composite adsorbent for pfas treatment, preparation method and application thereof

Abstract

The present disclosure discloses a COF aerogel composite for PFAS treatment, preparation method and application thereof, which falls within the field of pollutant adsorption. The composite comprises the following components: 68.18%-70% COF material, 22.73%-90.91% Chitosan solution, and 9.09% trialdehyde phloroglucinol solution. The COF material consists of ETTA (0.0764 mmol, 30 mg), a side functional monomer (0.1528 mmol), and an o-dichlorobenzene/n-butanol solvent (3 mL), wherein the volume ratio of o-dichlorobenzene to n-butanol in the solvent is 1:1, the side functional monomer includes 0.025 mmol TFTDA and 0.127 mmol BFBIM, and the resulting material is designated as COF-F1N5. The series of COF/aerogels synthesized in this present disclosure exhibit ultralight weight, compression resistance, high stability, and minimal specific surface area loss. This overcomes the application limitations of COF powders, facilitates recyclability, and demonstrates excellent adsorption performance toward PFAS.
