| Abstract:A functionalized cellulose-based aerogel （Cell@PEI） with high adsorption efficiency for p-arsanilic acid （p-ASA） was fabricated by crosslinking surface ammoniated polyethyleneimine （PEI） with cellulose. The results showed that the three-dimensional massive Cell@PEI had a unique porous structure with a large specific surface area of 241.4 m2/g. Moreover， the introduction of PEI enriched the functional groups on the surface of the aerogel， enhanced the electrostatic interaction and hydrogen bonding in Cell@PEI， promoting the adsorption towards p-ASA. The adsorption capacity of Cell@PEI was 205.6 mg/g in maximum， which was in accordance with the Freundlich adsorption isotherm model and pseudo-second-order adsorption kinetics model. In addition， the removal of p-ASA was still above 70% by Cell@PEI aerogel after desorption and regeneration in NaOH solution for 5 times. |
