Abstract:The adsorption performances for bisphenol A onto the hypercrosslinked resin with two kinds of the hydrogen bond site of acetamino group and hydroxyl group was studied. The hypercrosslinked resin modified with acetaminophen was synthesized with chloromethylated polystyrene and acetaminophen by Friedel-Crafts reaction. Dichloroethane was used as solvent and ferric chloride was used as catalyst. The structures of the hypercrosslinked resin were characterized. The acetaminophen was successfully modified into the hypercrosslinked resin that revealed by the Infrared spectra. Comparison with the chloromethylated polystyrene, the BET surface area and pore volume of the hypercrosslinked resin modified with acetaminophen was increased significantly, the pore size was much smaller. The adsorption capacity of bisphenol A onto the hypercrosslinked resin was obviously superior to polysulphone micro-ball embedded with 75% activated carbon. Heat was discharged during the adsorption and the adsorption occurred automatically. The resin could be desorbed with 100% ethanol. The desorption rate of 100% ethanol was up to 99.92%. The adsorption kinetic date of bisphenol A was fitted to the first order rate equation. The intrapartical diffusion of bisphenol A was the main rate-controlling step. Adsorption rate was also affected by the impact of film diffusion.
