Theoretical consideration of the sorption of complexones on sulfo cation exchangers in displacement complexation chromatography

A mathematical model is proposed for describing the sorption of complexones (compositions of the solid and liquid phases, the elution order from the zone of sorbed complexone). The sorption of diethylenetriaminepentaacetic acid (DTPA) is considered as an example. In terms of this concept, experimental data reported by some Russian and foreign researchers are interpreted.
