Zusatztext "The book has been presented by well known scientists ? presents very interesting material ? The book as a whole will certainly be a useful source of information for numerous analytical chemists which are obliged to work in the timely important field of chemical analysis." - Adam Hulanicki! in Chem. Anal! Vol. 52! No. 157! 2007 Informationen zum Autor Ali\! Imran; Aboul-Enein\! Hassan Y. Klappentext Instrumental Methods in Metal Ion Speciation provides comprehensive coverage of the distribution! toxicities! and techniques of metal ion speciation. The authors discuss techniques such as gas and liquid chromatography! capillary electrophoresis! and both electrochemical and radiochemical methods. They present a range of liquid chromatographic approaches! including capillary electrochromatography and high-performance! ion! ion pair! micellar electrokinetic! size exclusion! chiral! and supercritical fluid chromatographies. The text also covers the principles of metal ion speciation! sample preparation! and metal ion speciation into environmental and biological samples using various techniques.
