Determination 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 کاملInvestigation and determination of lead concentration in liver of Platycephalus indicus in Minab, Qeshm Island and Khamir Port (Persian Gulf)
This study was conducted to determine concentration of lead (Pb) in the liver of flathead (Platycephalus indicus) in Minab, Qeshm Island and Khamir Port in the Persian Gulf during winter and summer (n= 30). Concentration of lead was measured using Atomic Absorption Spectrometry (AAS). The results showed that, there were significant differences between stations for the concentration of lead in ...
متن کاملA fully automated flow injection atomic absorption system for the determination of copper traces in waters with on-line pre-concentration in an ion-exchange column
The paper describes the development of an automatic on-line column pre-concentration technique using a time based-flow injection atomic absorption spectrometry system. A manifold incorporating a micro-column containing 25 mg of Dowex 50W-X8 was used with a time-based injector for the pre-concentration and determination of copper in natural and drinking waters. The system features depend on the ...
متن کاملRapid Determination of Lead in Urine by Ion Exchange.
For routine screening of employees in the lead industry, a method for determination of urinary lead was developed in which this element is removed from urine by means of a chelating agent, eluted, and determined by a modified dithizone method. The method gives values which are about 5% below those obtained by the wet ashing technic, with a precision of ± 2.1% in the range of 2-15 jig. of lead p...
متن کاملA flow system for the spectrophotometric determination of lead in different types of waters using ion-exchange for pre-concentration and elimination of interferences.
A flow system for the spectrophotometric determination of lead in natural and waste waters is proposed. The determination is based on the colorimetric reaction between malachite green and iodide, followed by the formation of a ternary complex between those reagents and lead cations. The developed flow system includes a lead pre-concentration step in a column packed with a cationic resin (Chelex...
