摘要:
An ion exchangeable mixture containing a polymeric compound consisting of an ion exchange resin, an acrylamide mixture containing at least one bisacrylamide and at least one acrylamide, and a copolymer obtained by reacting the polymeric compound with the acrylamide mixture, and a method of producing the same are provided. The ion exchangeable membrane produced by using the ion exchangeable mixture has significantly smaller electric resistance than conventional ion exchangeable membranes, and has excellent selective permeability because the ion exchangeable membrane is electrically charged. The ion exchangeable membrane can be produced under very mild production conditions, and thus can be produced very easily. Furthermore, the ion exchangeable membrane can be also formed into film during a crosslinking reaction in a solvent of water, and thus is advantageous in that the ion exchangeable membrane can be freely produced into desired sizes, shapes and forms.

An electrodialysis apparatus includes a sample chamber including first and second dialysis membranes and filled with a sample between the first dialysis membrane and the second dialysis membrane, an anode chamber including an anode and filled with a first chamber solution between the anode and the first dialysis membrane, and a cathode chamber including a cathode and filled with a second chamber solution between the cathode and the second dialysis membrane. In particular, when a voltage is applied to the anode and the cathode, ionic materials of the sample move to the anode and cathode chambers.
