The Thermo Scientific iCE 3000 Series Atomic Absorption Spectrometers are the ideal tool for the accurate and rapid determination of multiple trace elements in rice products. Flame atomic absorption can be used as a fast screening tool for the analysis of nutritional elements such as copper, manganese and zinc, while graphite furnace atomic absorption can be used for the accurate determination ...

A sensitive and simple method for the determination of trace amounts of indium in water samples by graphite furnace atomic absorption spectrometry (GFAAS) after coprecipitation with chitosan was investigated. Indium was quantitatively preconcentrated from water samples by coprecipitation with chitosan at pH 7.0-9.0. The coprecipitant was easily dissolved with acetic acid, and indium in the resu...

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 ...
