چکیده
This broad overview covers the use of gas and liquid chromatography as well as capillary electrophoresis for the determination of metal ions and metalcontaining species, such as organometallic compounds or metalloproteins. We pay particular attention to the latest developments and consider the features of the various detection techniques and applications of the different methods. a 2005 Elsevier Ltd.

متن کاملAdvances in instrumental methods for the measurement and speciation of trace metals.
Progress in understanding the role of trace metals in biology has been largely dependent on the development of sensitive, accurate and precise analytical methods. Atomic spectroscopic techniques, particularly atomic absorption, have made the greatest contribution. Key to the success of such analytical techniques has been the simplification of sample processing so that contamination is minimized...

Iron is quantitatively retained on an adsorbent made by coprecipitation of 1,2-dihydroxybenzene-3,5-disulfonic acid (Tiron) and tetradecyldimethylbenzylammonium choride (TDBA) an microcrystalline naphthalene as a slurry or packed in a column, in the pH range 6.0-9.0 from a large volumes of aqueous solutions (up to 200 ml on microcrystalline naphthalene and up to 500 ml of aqueous solutions ...
متن کاملChemically-Modified Activated Carbon with L-Arginine for Selective Solid Phase Extraction and Preconcentration of Metal Ions
In this study, a new sorbent of chemically-modified activated carbon with L-arginine (AC-Arg) has been produced as solid-phase extraction, to trace Zn(II) and Cd(II) ions in real samples, including soil and water samples, by Flame Atomic Absorption Spectrometry (FAAS). Once the surface coverage value is determined, the surface modification has been investigated and assessed, while having em...
