- An anion exchanger has been described by grafting dimethylaminoethyl methacrylate methylchloride (DMC) onto the poly(glycidyl methacrylate-divinylbenzene) (GMA-DVB) subtract. The grafting was performed by coupling of DMC with the pendant double bonds of DVB. Prior to grafting, a hydrolysis treatment to free epoxide groups associated with GMA-DVB substrate enables an improved hydrophilic surface of the obtained anion exchanger. The capacity of the obtained anion exchanger can be manipulated by controlling DMC amount to a great degree. Common seven inorganic anions onto the anion exchanger could be well separated within 20 min and high separation efficiency was obtained, e.g. 46,500/m of the plate count for chloride.
