Frintctl in The Ncthcrlands CHIWltl. 6453 RAPID AND CONTINUOUS DI?=TISRhiINATION 01: METAL IONS BY CATION-EXCHANGE CHROMATOGRAPHY Metal ions can be rapidly separated from each other using forced-flow cationexchange chromatography with solutions of hydrochloric acid in z-propanol-water or acetone-water as the eluent, The elutcd peaks are detected and recorded after adcling a color-forming reagent and mixing it with the effluent stream. A mixture containing seven different metal ions was separated in approximately 25 min.

Alkali metals have been determined in many ways, but for trace analysis two methods are normally applied: spectrometry and activation analysis. Both flame emission and atomic-absorption spectrometry are very suitable for the trace analysis of alkali metals. Detection limits in the p.p.b, range 1-3 c
