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 ...

15 صفحه اولSimultaneous direct determination of aluminum, calcium and iron in silicon carbide and silicon nitride powders by slurry-sampling graphite furnace AAS.
A fast and accurate analytical method was established for the simultaneous direct determination of aluminum, calcium and iron in silicon carbide and silicon nitride powders by graphite furnace atomic absorption spectrometry using a slurry sampling technique and a Hitachi Model Z-9000 atomic absorption spectrometer. The slurry samples were prepared by the ultrasonication of silicon carbide or si...
متن کاملDEVELOPMENT 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...
