Analytical Chemistry Division Commission on Microchemical Techniques and Trace Analysis* Working Group on Speciation? Determination of Arsenic Species in Environmental and Biological Samples
ثبت نشده
چکیده
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 methods applicable to a specific matrix evaluating hydride generation technique, high performance liquid chromatography coupled with atomic absorption, ICP atomic emission, ICP mass spectrometric detection, thin layer and gas chromatography with atomic absorption spectrometric area that requires attention as it still represents the main source of problems including matrix interference, incomplete recovery and analyte instability. detection and other methods. Sample preparation is the

Arsenic, Antimony, Chromium, and Thallium Speciation in Water and Sediment Samples with the LC-ICP-MS Technique
Chemical speciation is a very important subject in the environmental protection, toxicology, and chemical analytics due to the fact that toxicity, availability, and reactivity of trace elements depend on the chemical forms in which these elements occur. Research on low analyte levels, particularly in complex matrix samples, requires more and more advanced and sophisticated analytical methods an...

Analytical chemistry of metal complexes with biomacromolecules based on the coupling of a high resolution separation technique with an element or species selective detection technique is critically discussed. The role of size-exclusion chromatography (SEC) with on-line atomic spectrometric detection is evaluated for the characterization of the metal distribution among the fractions of different...
متن کاملAnalytical methods for arsenic speciation analysis
Arsenic exists in the form of various chemical species differing in their physicochemical behaviour, toxicity, bioavailability and biotransformation. The determination of arsenic species is an important issue for environmental, clinical and food chemistry. However, differentiation of these species is a quite complex analytical task. Numerous speciation procedures have been studied that include ...
