Determination of Trace Amounts of Iron and Chromium in Alminium Nitride by Graphite-Furnace Atomic Absorption Spectrometry

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 ...

GRAPHITE 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...

Determination of Trace Elements in Rice Products by Flame and Graphite Furnace Atomic Absorption Spectrometry

The Thermo Scientific iCE 3000 Series Atomic Absorption Spectrometers are the ideal tool for the accurate and rapid determination of multiple trace elements in rice products. Flame atomic absorption can be used as a fast screening tool for the analysis of nutritional elements such as copper, manganese and zinc, while graphite furnace atomic absorption can be used for the accurate determination ...

Utilization of electrodeposition on a graphite probe modified with palladium in determination of lead by graphite furnace atomic absorption spectrometry in water and environmental samples

In this work a rapid and selective procedure for separation and preconcentration of lead(Pb2+) before determination by electrothermal atomic absorption spectrometry (ETAAS) wasdeveloped. The procedure is based on the electrodeposition on a graphite probe modified withpalladium. The lead was deposited from acetate buffer solution at pH 5.5. Various parameters,such as pH of solutions, deposition ...
