Ion exchange is a fundamentally important mode of liquid chromatography, forming the basis of many modern analytical methods, from solid phase extraction and sample clean-up, to modern high-performance ion chromatography. A number of significant books and monographs exist on each of these ion exchange based technologies, detailing fundamental aspects of the exchange process, methodology and their analytical and industrial applications. Traditionally ion exchange is viewed as a technique based upon the exchange of ions between phases, where retention on a stationary phase is predominantly based upon simple electrostatic attraction. However, in cation exchange chromatography a significant variation from simple cation exchange exists, where the retention of cations is no longer dominated by electrostatic attraction, but instead is controlled through the formation of metal-ligand bonds with immobilised ligands, forming metal-ligand complexes, or chelates, on the stationary phase surface. Chelating stationary phases are those which are capable of forming such complexes, and are available in many variations for both classical and analytical chromatographic application. In this monograph we selectively detail the wide and varied application of chelating ion exchange materials to the ‘high-performance’ separation of metal ions. As ‘ion chromatography’ has naturally evolved as the descriptive name to describe high-performance separations achieved based upon all modes of ion exchange, here we collectively describe as ‘chelating ion chromatography’ all those methods based upon chelating ion exchange phases for the high-performance liquid chromatographic separation of metal ions. This descriptive definition specifically excludes the significant body of work on chelating phases for extraction, batch separation, concentration and classical chromatographic applications, which is also well documented elsewhere. The monograph provides the reader with a detailed description of the fundamental theory of the chelating exchange mechanism, the impact of thermodynamics and kinetics on the chelating exchange process, the physical and chemical requirements for efficient chromatographic separations of metal ions and the selectivity offered by the wide and varied range of chelating ligands utilised in this significant field of ion chromatography. The authors of this monograph have worked both together and individually on chelating stationary phase materials and their chromatographc applications for over two decades, having published a significant number of joint papers on the subject. The authors have now come together again to publish this definitive and unique resource for all those analytical scientists, bio-analysts, chemical engineers and chromatographers working on the analysis of metal ions in complex and challenging matrices.
