Atomic Absorption Spectrometric

Abstract A method for the determination of manganese in blood and animal tissue has been developed involving wet digestion of the sample by perchloric and nitric acids, complexing with sodium diethyldithiocarbamate, and extracting with methyl isobutyl ketone at pH 6.7. The methyl isobutyl ketone is removed, and the residue is dissolved in 0.05N HCl in acetone-water (9+1) and is aspirated into an air-acetylene flame of an atomic absorption spectrometer. The limit of detectability is about 10 ng Mn/ml in the solution aspirated or 2 ng Mn/ml in bovine blood for a 20 ml sample.

Ionic Associates

A new method has been developed for the indirect determination of nitroso- and nitrophenols by atomic absorption spectrometry (AAS) after extraction of ionic associates involving bipyridylocopper(II) (CuDP) or phenanthrolinocopper(II) (CuPH) complexes. Nitrobenzene and methyl isobutyl ketone appeared to be suitable for the extraction. It was possible to determine several tenths to hundredths of a milligram of nitrophenol in a litre. Extractable associates with CuDP and CuPH are formed by phenols possessing two substituents or by higher molecular weight phenols such as naphthol or hydroxyquinoline. Monosubstituted phenols fail to form associates of this kind.

An atomic absorption method is described whereby the gold excreted in the urine of patients undergoing chrysotherapy can be estimated. Gold is precipitated as telluride, dissolved in aqua regia, and extracted into methyl isobutyl ketone for estimation by atomic absorption spectroscopy using graphite furnace atomization.
