Analytical procedure for the quantitative determination of Mg in Al-alloys using ion-exchange thin layer chromatography is described. Chromatographic plates were coated with Amberlite IRP-69 (strong-acid cation exchanger in H[sup +]-form) mixed in different ratios with microcrystalline cellulose. Solutions of HCl and HNO[sub 3] respectively, in the concentration range from 0.5-2.0 mol dm[sup [minus]3] were used as developers. Chromatograms were visualized by spraying with ethanolic solution of 8-hydroxyquinoline and spots were scanned using Camag Turner Fluorometer 111. The optical separation was obtained on TLC plates containing 23% of ion-exchanger (particle size < 60 [mu]m) and by eluting with 1.25 M HCl. R[sub F] (Al) = 0.12, R[sub F](Mg) = 0.41.
