Application of flow injection on-line electrothermal atomic absorption spectrometry to the determination of rhodium.
A fully automated procedure for the determination of rhodium has been developed using flow injection (FI) on-line microcolumn preconcentration coupled with electrothermal atomic absorption spectrometry (ETAAS). The proposed FI manifold and its operation make possible the introduction of the total eluate volume into the graphite atomizer, avoiding the necessity for optimisation of subsampling th...
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 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...
متن کاملFlow injection hydride generation electrothermal atomic absorption spectrometry with in-atomizer trapping for the determination of lead in calcium supplements.
Lead hydride was generated from acid solution, containing potassium ferricyanide as an oxidizing agent, by the reaction with alkaline borohydride solution. The effects of reaction conditions (hydrochloric acid, ferricyanide and borohydride concentrations), and the lengths of reaction and stripping coils were studied. The effects of trapping temperature and argon flow rate were also investigated...
متن کاملOn-line Preconcentration of Nickel by Carbonyl Vaporization With Flow Injection and Continuous Flow Systems in Combination With Sensitive Determination by Electrothermal Atomic Absorption Spectrometry
A sensitive method is described for the on-line determination and preconcentration of nickel using the coupling of a flow system (continuous flow and flow injection) with transversely heated electrothermal atomic absorption spectrometry. The method is based on the volatilization of nickel as nickel tetracarbonyl and its trapping on a graphite surface. The carbonyl generation is optimized by usi...
