Determination of Gold by High-Resolution Continuum Source Atomic Absorption Spectrometry with Chemical Vapor Generation
Avaliou-se o potencial analítico da geração de vapor químico e da espectrometria de absorção atômica com fonte contínua de alta resolução com atomização em tubo de quartzo na determinação de ouro. As espécies voláteis de ouro foram formadas pela reação com tetraidroborato(III) de sódio na presença de ácido clorídrico. Investigou-se a influência de brometo de didodecil dimetilamônio (DDAB) e die...
متن کاملDetermination of lead in wine and rum samples by flow injection-hydride generation-atomic absorption spectrometry.
A method for direct determination of lead in wine and rum samples was developed, using a flow injection hydride generation system coupled to an atomic absorption spectrometer with flame-quartz atomizer (FI-HG-AAS). Lead hyride (PbH(4)) was generated using potassium ferricyanide (K(3)Fe(CN)(6)), as oxidant and sodium tetrahydroborate (NaBH(4)) as reductant. Samples were acidified to 0.40% (v/v) ...
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 lead and cadmium in water samples by cloud point extraction prior to flame atomic absorption spectrometry determination
Pb and Cd in water samples were determined by cloud point extraction (CPE) with sodiumdiethyldithiocarbamate (DDTC) as the chelating agent and octylphenoxypolyethanl (Triton X-114) asthe surfactant prior to flame atomic absorption spectrometry (FAAS) determination. The main factorsof affecting the extraction and detection processes were optimized. The preconcentration of 10 mL ofstandard soluti...
متن کاملDetermination of Total Mercury by Vapor Generation In Situ Trapping Flame Atomic Absorption Spectrometry
The analytical performance of non-chromatographic coupled hydride generation, integrated atom trap (HG–IAT) atomizer flame absorption spectrometry (FAAS) systems were evaluated for the determination of total mercury in environmental samples. Mercury, using formation of mercury vapors were atomized in air-acetylene flame-heated IAT. A new design of vapor generation integrated atom trap flame ato...
