Micelle exclusion chromatography of heavy-metal cations

· Anal. Chem.; (United States)
Micelle exclusion chromatography, wherein a micellar mobile phase and a size exclusion column are utilized for ionic separation, was applied to the separation of heavy-metal cations. Usefulness of simple micelle exclusion chromatography was limited by the poor resolution of metal cations, but addition of complexing agents in the sodium dodecyl sulfate eluent made possible the simultaneous separation of many divalent and trivalent transition- and rare-earth-metal cations. Additionally, the chromatographic retention behavior was used to calculate partition coefficients of metal ions between micelles and the bulk solution and between the imbibed solution and the stationary phase.
