Abstract
Summary: The comparative and supplementary investigations for the determination of traces of germanium by extraction-spectrophotometry and atomic absorption spectrometry serve for the development of suitable multi-stage combined procedures for the analysis of biological samples. The improved spectrophotometric determination by phenyl-fluorone after extraction of germanium tetrachloride with CCl4 instead of MIBK is of higher precision. A detection limit of 5 ng Ge ml−1 with s=±6% was obtained. The investigations for the determination of germanium by atomic absorption spectrometry with electrothermal atomisation show the best sensitivity using alkaline samples or in the presence of an oxidant, e.g. nitric acid or nitrates. Interferences caused by several salts may be eliminated for the most part with palladium nitrate and magnesium nitrate as modifier. The detection limit is 20 ng Ge ml−1 with a relative standard deviation of ±8%.
