[Advances of electrodialytic technologies used in ion chromatography].

An electrodialysis device is used to transport salt ions from one solution to another through an ion-exchange membrane under the influence of an applied electric potential. They can produce hydronium or hydroxide ions via electrodialysis water, which can be used for online preparation of eluents or suppression or detection in ion chromatography (IC). As opposed to the manual preparation of eluents or regenerant solutions, electrodialysis devices have the advantages such as green, efficient and high purity. Thus, IC systems equipped with electrodialysis devices dominate the majority uses of IC system, and more importantly, find widespread application. The present thesis briefly summarizes the latest developments in this area.
