Determination and Levels of Chromium in French Wine and Grapes by Graphite Furnace Atomic Absorption Spectrometry
An accurate and precise method for direct determination of chromium in wine using graphite furnace atomic absorption spectrometry (GFAAS) is described. The method was also applied to grape samples treated by previous acid mineralization. A total of 79 wine samples from different regions in France and 12 grape samples of different varieties were analyzed. Chromium levels ranged from 7.0 to 90.0 ...
متن کاملGRAPHITE FURNACE ATOMIC ABSORPTION SPECTROMETRY WITH MAlIlRIX MODIFICATION FOR DETERMINATION OF LEAD IN DRINKING WATER
An amoniumvanadate plus sodium molybdate mixed modifier Graphite Furnace Atomic Absorption Spectrometric method has been developed for determination of traces of lead in drinking water. The concentration of lead in the sample is obtained by direct comparison to linear working graph prepared from aqueous standards in the modifier medium, The results indicate the better performance of the pro...
متن کاملdirect determination of arsenic in potassium citrate tablet using graphite furnace atomic absorption spectrometry
in this study, a rapid and simple method based on graphite furnace atomic absorption spectrometry (gfaas) is described for direct determination of arsenic in potassium citrate tablet samples. pyrolytic graphite tubes were used as atomizers. nickel nitrate was used as chemical modifier. the ashing and atomization temperature and the concentration of modifier were also optimized. the detection li...
متن کاملDetermination of lead, copper and manganese by graphite furnace atomic absorption spectrometry after separation/concentration using a water-soluble polymer.
In this study, a water-soluble polymer, polyvinylpyrrolidinone (PVP) having chelating functionalities was used for the preconcentration and separation of traces of Pb, Cu, Ve and Mn prior to their determination by graphite furnace atomic absorption spectrometry. For this purpose, the sample and the PVP solutions were mixed and the metal bound polymer was precipitated by adding the mixture onto ...
متن کاملMultivariate Optimization in the Direct Determination of Antimony and Chromium in Serum Samples by Graphite Furnace Atomic Absorption Spectrometry
Methods for direct determination of antimony and chromium in human serum by Graphite Furnace Atomic Absorption Spectrometry (GF AAS) were proposed in this work. The samples were diluted in 1:1 with nitric acid 1% v/v and Triton® X-100 0.1% v/v. The optimization of the instrumental conditions was done using a multivariate approach. A factorial design (2) was employed to investigate the tendency ...
