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...
متن کاملIron and selenium speciation in enriched adzuki bean sprouts by graphite furnace atomic absorption spectrometry
The production of edible sprouts is a fast-growing segment of the food industry worldwide. Although several kinds of seeds may be eaten as sprouts, adzuki (Vigna angularis) and mung (Vigna radiata) beans are preferred and commonly used for sprout production.1 Studies have shown that grain germination increases the content of essential nutrients, such as minerals, vitamins, and proteins, and red...
متن کاملComparative measurement of gas temperature in a graphite atomizer by a two-line method of iron and nickel spectral lines in graphite furnace atomic absorption spectrometry.
The gas temperature of atomospheric gas in a graphite atomizer was measured during an atomization stage in graphite furnace atomic absorption spectrometry (GF-AAS), by using a two-line method under the assumption of Boltzmann distribution. Iron and nickel were chosen as the probe elements to compare the gas temperatures obtained with different pairs of spectral lines. The atomic absorptions of ...

متن کاملUtilization 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 ...
