Slurry sampling of sediments for direct determination of Cu, Mn, Ni, Sn and Zn by graphite furnace atomic absorption spectrometry
In this study, methodologies were developed for the determination of metals (Cu, Mn, Ni, Sn and Zn) in sediments prepared as slurries, which were maintained homogeneous by the introduction of air supplied by an aquariam pump by GF AAS (Graphite Furnace Atomic Absorption Spectrometry). The optimization of the pyrolysis and atomization temperatures were done through pyrolysis and atomization temp...
متن کاملThe Reduction of Matrix Interferences Utilizing the Platform in Graphite Furnace AAS
Graphite furnace techniques are characterized by excellent analytical sensitivity and are the methods of choice for the determination of trace elements in various environmental, biological, and clinical samples. However, they can be plagued by matrix interferences which complicate methods development and sample analysis. This is particularly true for the determination of volatile elements in co...
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 ...
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...
متن کاملEvaluation of a New Forked Platform Design for Graphite Furnace AAS Authors
Graphite furnace techniques are characterized by excellent analytical sensitivity. They are methods of choice for the determination of trace elements in various environmental, biological, and clinical samples. However, they can be plagued by chemical and background interferences which complicate methods development and sample analysis. Using the graphite platform technique, these interferences ...
