title: Thin-layer chromatographic separation of alkaline earth metals on microcrystalline cellulose.
abstract: The thin-layer chromatographic behaviour of all the alkaline earth metals except for radium on microcrystalline cellulose in methanol-nitric acid media has been investigated. The R(f) values increase in the order beryllium > magnesium > calcium > strontium > barium. The five metals can be effectively separated from each other with methanol-14M nitric acid (3:1, v/v). The system is also suitable for the separation of mixtures of two metal ions existing in widely varying proportions.
