15 صفحه اولGRAPHITE 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 کاملDetermination of cadmium in wine by electrothermal atomic absorption spectrometry.
A method is described for direct electrothermal atomic absorption spectrometric (ETAAS) determination of cadmium in untreated samples of wine. Pyrolytic graphite tubes and graphite tubes with standard L'vov pyrolytic platforms were tested as atomizers. The detection limit achieved was 0.08 microg L(-1) Cd in wine. The relative standard deviation for the concentration range from 0.2 to 10 microg...
متن کاملDetermination of arsenic in seafood by electrothermal atomic absorption spectrometry after microwave digestion: NMKL collaborative study.
Eight laboratories participated in an interlaboratory method performance (collaborative) study of a method for the determination of arsenic in foodstuffs of marine origin by electrothermal atomic absorption spectrometry after wet digestion using a microwave oven technique. The study was preceded by a practice round of familiarization samples. The method was tested on 8 materials (cod roe, krill...
متن کاملAutomated on-line separation–preconcentration system for platinum determination by electrothermal atomic absorption spectrometry
A flow injection on-line sorption preconcentration system for the electrothermal atomic absorption spectrometric determination of platinum has been developed. The method employs on-line preconcentration of platinum on a column packed with silica gel functionalised with 1,5-bis(di-2-pyridyl)methylene thiocarbohydrazide (DPTH-gel) placed in the autosampler arm. The modification of the autosampler...
