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.

AbstractA chemical separation system was developed to separate group 4 and 5 elements using extraction from HCl/HF solution into methyl-isobutyl-ketone (MIBK). The system is proposed to be applied for a confident assignment of the spontaneous fissioning radionuclide produced as decay product of element 115 either as dubnium (Db,

Furnace Atomization

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.

Absorption Spectrophotometry

Caviar and dried apricots containing a known amount of added boric acid were subjected to a collaborative study. The samples were digested with sulfuric-nitric acid under reflux; the boron was then complexed with 2-ethyl-1,3-hexanediol and extracted into methyl isobutyl ketone. Boron in the organic phase was determined by atomic absorption, using a nitrous oxide-acetylene flame. The recoveries were satisfactory: 103, 95, and 93% for 300, 1000, and 1600 μg boron/g apricots and 95, 90, and 92% for the corresponding caviar samples. The method has been adopted as official first action.
