Speciation of Antimony in Waters Using Separation Coupled with Atomic Spectrometry

Abstract

The interest in the determination of different Sb species in natural waters is due to the fact that their toxicological and physiological behavior strongly depends on their chemical forms and oxidation states. The purpose of this article is to review and evaluate methods for Sb speciation in waters based on selective hydride generation of Sb(III) and on coupling of different separation techniques (liquid-liquid extraction, solid phase extraction, cloud point extraction, ion-exchange HPLC and GC) with atomic spectrometric methods (AAS, atomic emission spectrometry and atomic fluorescence spectrometry). This review covers the literature published over the period 1998-2006.
