Abstract.

 An on-line method for the separation and analysis of Sb(V) and Me3Sb in the presence of Sb(III) in liquid samples is described. Inorganic and organic antimony species were separated using anion-exchange high-performance liquid chromatography (HPLC) coupled with hydride generation-atomic fluorescence detection (HG-AFS). Optimum conditions for the separation of antimony species by HPLC and the hydride generation conditions for the determination by HG-AFS were established. Matrix interference of the chromatographic determination was studied in relation to MgSO4 and NaCl. The method developed was applied to the separation and determination of antimony species in spiked and natural water samples. The suitability of the method for analysis in microbial growth media and physiological studies involving methylantimony species is discussed.
