Abstract
A combined procedure for determination of macrocontents of palladium in various palladium-containing objects such as platinum metal alloys and palladium salts and complex compounds is proposed. The procedure is based on a combination of the gravimetric precipitation of palladium by dimethylglyoxime followed by determination of the residual content of palladium in the filtrates by atomic absorption spectrometry. A number of generalizations and technological conclusions are made that enable simplification of the procedure and reduction in the analysis time. On the basis of standardized test mixtures, it is shown that the relative analysis error according to the proposed procedure does not exceed 0.2%, which is practically in agreement with the error of classical gravimetric analysis.
