摘要
HCP resin was prepared by Friedel- Crafts reaction with chloromethylated polystyrene(PS- Cl) as precursor and applied to the adsorption of isoamyl alcohol. The results of scanning electron microscope, infrared spectrum, X-ray diffraction, thermal stability and specific surface area analysis show that the HCP resin has smooth spherical surface, the carbonyl groups are introduced, the crystal form is almost unchanged, the thermal stability is enhanced, the specific surface area is increased to 955.83 m2/g, and the microporous specific surface area accounts for 65.03% of the BET specific surface area. It is proved that the HCP resin prepared by Friedel-Crafts reaction at 85℃ for 4 h has the best adsorption effect on isoamyl alcohol; the adsorption thermodynamics of HCP resin for isoamyl alcohol is more consistent with Freundlich model, and the adsorption is endothermic, and the adsorption kinetics belongs to quasi second- order kinetic adsorption; the adsorption capacity after five cycles is 82.31% of the first adsorption capacity, indicating that HCP resin has good regeneration and recyclability. ? 2022, Editorial Board of Polymer Materials Science & Engineering.
