Abstract
The system for on-line microcolumn sorption preconcentration and induc tively coupled plasma atomic emission spectrometry determination of 14 rare earth elements (REEs) is described. Aminocarboxylic sorbents of different structure are used. Preconcentration of REEs from the 20 ml of sample solution and elution with 210 mu l of 1 mol l(-1) HCl result s in an enrichment factor of 99. The detection limit of REEs is about nx 0.1 mu g l(-1) (RSD 3-5%). The possibility of simultaneous REE dete rmination in complicated solutions is demonstrated.
