Through chloromethylated and cross-linked polystyrene being moderately Friedel-Crafts post-cross linked and then aminated,a series of new macroporous resins,which have larger physical surface area and some alkalescent ion-exchanged groups,were produced.The best resin WXA-8is selected from those resins and the results also showed that the static equilibrium adsorption capacity of WXA-8 for the baicalin solution (1750 mg/L)is 190.3 mg/g.
