High Performance Liquid Chromatography of Metal Chelates

Abstract

Abstract Liquid chromatography, especially ion-exchange chromatography, has been used very successfully for the separation of ionic metal chelates for many years. More recently, ion chromatography, an ion exchange method proposed by Small et al. (1) in 1975 for the determination of ionic species at low concentrations has undergone a period of rapid growth. Fritz (2) has recently published a book on ion chromatography which reviews work done in this field. Classical chromatographic methods for the separation of inorganic species and metal chelates has been reviewed by Michal (3) and, the somewhat more recently developed, reversed-phase extraction chromatographic methods by Cerrai and Ghersini (4) and Braun and Ghersini (5).
