一种生物质干凝胶及其制备方法和应用
By preparing biomass dry gel materials, a framework is formed by cross-linking quaternized cellulose and chitosan, and fluorinated silicon oxides are attached to the framework. This solves the problem of poor adsorption performance of existing adsorbents for short-chain and ultra-short-chain PFAS, and achieves efficient and sustainable PFAS removal.

AI Technical Summary
Existing adsorbent materials have poor adsorption performance for short-chain and ultra-short-chain perfluorinated and polyfluorinated alkyl substances (PFAS), and also suffer from problems such as high cost and poor stability.
Biomass dry gel material is used, and a framework is formed by cross-linking quaternized cellulose and chitosan. Fluorinated silicon oxygen groups are attached to the framework, and the adsorption performance is optimized by utilizing their electrostatic interaction and steric hindrance.
It achieves efficient removal of short-chain and ultra-short-chain PFAS, with good anti-interference ability, structural stability and renewability, reducing raw material costs and improving the sustainability and resource utilization level of materials.
