Abstract:Polystyrene-arginine chelating resin was synthesized by hydrolytic reaction of chloromethylated polystyrene with arginine. The pore volume, pore size and specific surface area of the resin were measured, and its adsorption properties of theophylline in aqueous solution was studied. The results showed that the adsorption amount of arginine resin to theophylline was 21.05 mg·g -1.
Key words:polystyrene; adsorption; resin; theophylline
