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 کاملStudy of the roles of chemical modifiers in determining boron using graphite furnace atomic absorption spectrometry and optimization of the temperature profile during atomization.
The measurement conditions for determining boron using graphite furnace-atomic absorption spectrometry (GF-AAS) were investigated. Differences in the boron absorbance profiles were found using three different commercially available GF-AAS instruments when the graphite atomizers in them were not tuned. The boron absorbances found with and without adjusting the graphite atomizers suggested that a...
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 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 کاملMeasuring Conditions for the Determination of Lead in Iron-Matrix Samples Using Graphite Atomizers with/without a Platform in Graphite Furnace Atomic Absorption Spectrometry
In graphite furnace atomic absorption spectrometry (GF-AAS), the atomization process of lead occurring in graphite atomizers with/without a platform plate was investigated when palladium was added to an iron-matrix sample solution containing trace amounts of lead. Absorption profiles of a lead line were measured at various compositions of iron and palladium. Variations in the gas temperature we...
