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...

Analysis of Low Lead and Cadmium Concentrations in Soil Extracts by Graphite Furnace Atomic Absorption Spectrophotometry

An analytical procedure was derived to provide an accurate measurement of low lead (Pb) and cadmium (Cd) concentrations in soil extracts using graphite furnace atomic absorption spectrometry (GFAAS). Based on peak area measurements and with background correction, the use of 2% phosphoric acid as chemical modifier enables the GFAAS to give measurements of Pb and Cd concentration as low as 3 fLg ...

The Analysis of Trace Elements in Honey by Flame and Graphite Furnace Atomic Absorption Spectrometry

Anodic stripping voltammetry compared with graphite furnace atomic absorption spectrophotometry for blood lead analysis.

According to a recent CDC report, blood lead concentrations in 1 000 000 US children are at values associated with irreversible damage to health (1 ). The effects of chronic lead poisoning on the developing nervous systems have been well documented (2 ), with children in inner city neighborhoods, where older housing stocks have deteriorating lead paint, most vulnerable (3 ). Accurate screening ...

DEVELOPMENT OF A METHOD FOR ALUMINIUM DETERMINATION IN SERUM AND DIALYSIS FLUID BY FLAMELESS ATOMIC ABSORPTION WITH GRAPHITE FURNACE

Aluminium determination was carried out in serum and dialysis fluid by a simple and reliable method of nameless atomic absorption with graphite furnace . . No preparatory procedures are required for water and dialysis fluid. In this method serum was mixed with 0.2% HNO, to allow complete combustion of the samples in order to improve analytical precision. The method has a sensitivity of 15 p...
