Abstract

Small quantities of silver in technical aluminum can be determined
by TLC on the layer of microcrystalline cellulose after
separation and concentration by coprecipitation with CdS. The
chromatograms were developed by a solvent composed of butanol-
methanol-water-nitric acid in the proportion 80 : 5 : 10 : 5 (v/v).
Visualisation was made with hydrogen sulfide. After scanning
the obtained spots, concentration of silver in the samples was
calculated by comparison with reference spots.
