    Summary: This research work was carried out to find then optimumconditions for anodic sampling of steels, aluminium alloys, brassetc. It was found using electrolyte: the water solution ofammon-nitrat (1 g/L) and hydrochloric acid (conc.) in volumeratio 1:1, give the best results if the duration ofelectrochemical process was 45 s and D.C. current was 4.4 V. The elements which are sampled were detected by thiun layerchromatography and optical emission spectrometry.

    Summary: The method of magnesium determination by means of thequantitative thin layer chromatography is presented. It is proventhat there exists a linear dependence of spot intensity ofmagnesium, visualized by spraying an 8-hydroxy-quinoline solution, on the mass of magnesium the spot within the magnesium massconcentration range between 0.05 and 0.5 g/L of magnesium.Magnesium is successfully separated from other interferingconstituents Al, Cu and Co if the mass concentrations of theseconstituents were under 0.5 g/L by using a developing mixture ofBuOH+EtOH+MetOH+conc. HCl in volume proportions 50:30:10:10. Thelower limit of mass concentrations which was measured was 0.05g/L of Mg, but the detection limit is 0.1 g/L.

    Summary: Analytical procedure for the quantitative determination of MG inAl-alloys using ion-exchange thin layer chromatography isdescribed. Chromatographic plates were coated with AmberlitIRP-69 (strong-acid cation exchanger in H-form) mixed indifferent ratios with microcristalline cellulose. Solutions ofHCl and HNO3 respectively, in the concentration range from0.5-2.0 mol dm-3 were used as developers. Chromatograms werevisualized by spraying with ethanolic solution of8-hydroxyguinoline and spots were scanned using Camag TurnerFluorometer 111. The optimal separation was obtained on TLCplates containig 23% of ion-exchanger (particle size < 60 um) andby eluting with 1.25 M HCl. Rf (Al)=0.12, Rf(Mg)=0.41.

    Summary: A specific interaction of copper(II) ion with hydrogen iodide taking place in the mobile phase (an acidified water/ButOH mixure) during the thin-layer chromatographic process was studied with the aim of formulating a TLC analytic method with enhanced specificity for Cu(II). A slip-chromatographic method for efficient separation of Cu(II) from other ions having similar Rf values was formulated and successfully applied for differentiang copper-containing Al alloys used for machine bearings from the copper-free ones.
    Keywords: copper,hydrogen iodide,slip chromatography,thin-layer chromatography
