Arsenic speciation by hydride generation-Quartz furnace atomic absorption spectrometry. Optimization of analytical parameters and application to environmental samples
Analytical parameters of hydride generation, trapping, gas chromatography and atomic absorption spectrometry detection in a quartz cell furnace (HG/GC/QFAAS) device have been optimized in order to develop an efficient and sensitive method for arsenic compounds speciation. Good performances were obtained with absolute detection limits in the range of 0.1 – 0.5 ng for arsenite, arsenate, monometh...
متن کاملSpeciation determination of arsenic in urine by high-performance liquid chromatography-hydride generation atomic absorption spectrometry with on-line ultraviolet photooxidation.
A coupled system for arsenic speciation determination based on high-performance liquid chromatography (HPLC), on-line UV photooxidation and continuous-flow hydride generation atomic absorption spectrometry (HGAAS) was built from commercially available modules with minor modifications to the electronic interface, the software and the gas-liquid separator. The best results were obtained with stro...
متن کاملArsenic determination in marine sediment using ultrasound for sample preparation.
This work deals with As determination in marine sediment using ultrasound for sample preparation. It is shown that As can be quantitatively extracted from marine sediment using 20% (v/v) HCl and sonication. The slurry is centrifuged and the analyte is determined in the supernatant by hydride generation atomic absorption spectrometry (HG AAS). A flow injection (FI) system is employed for hydride...
متن کاملSpeciation of Arsenic(III)/Arsenic(V) and Selenium(IV)/Selenium(VI) Using Coupled Ion Chromatography– Hydride Generation Atomic Absorption Spectrometry
Simple analytical methods have been developed to speciate inorganic As and Se in the microgram per liter range using coupled ion chromatography–hydride generation atomic absorption spectrometry. Because of the differences in toxicity and adsorption behavior, determinations of the redox states arsenite, As(III), and arsenate, As(V), and selenite, Se(IV), and selenate, Se(VI), are important. Anio...
متن کاملAnalytical Chemistry Division Commission on Microchemical Techniques and Trace Analysis* Working Group on Speciation? Determination of Arsenic Species in Environmental and Biological Samples
Identification and quantitative determination methods of arsenic species in environmental and biological samples are discussed. Isolation followed by molecular spectroscopic determination is necessary for rigorous identification while element-specific detections coupled with separation techniques are the choice for quantitative determination. Analytical figures of merit are given for the method...
