✦ Synopsis

In a Ixevious

palx+, an ion-exchange mcthocl was described for the quantitative separation of the alkaline earths from each other. This p;ll>er presents the application of the ion-exchange separation to the determination of the alkaline earths in glass.

Preliminary cxpcriments indicated that most of the clcmcnts of glass appear with the calcium in the first fraction of the eluatc. For this reason, it was dccmcd advisable to isolate the alkaline-earth group before the application of the chromatographic separation. Furthermore, overloading of the column was avoided by the group separation.

An cxchangc column, a.54 srl.cm in cross-section area, was filled to 8 depth of 19 cm with colloidal aggregates of Dowcx-go, lot 50572, previously passed through a xzo-mesh SICVC.~ Rcagcntgrade chemicals were used.

## Abstract An ion chromatographic method has been developed for the determination of alkali (Li^+^, Na^+^, K^+^), alkaline earths (Ca^2+^, Mg^2+^, Ba^2+^, Sr^2+^) and ammonium ion in waters. The usual difficulties encountered during traditional cation‐exchange separations (incomplete resolution fo
