Preconcentration of inorganic species of antimony by sorption on Polyorgs 31 followed by atomic absorption spectrometry detection

Environmental context. Antimony first attracted public attention in the mid-1990s amid claims that it was involved in Sudden Infant Death Syndrome. A substantial number of papers have now been published on the element and its behaviour in the natural environment. However, many key aspects of the environmental chemistry of antimony remain poorly understood. These include critical areas such as its ecotoxicology, its global cycling through different environmental compartments, and what chemical form it takes in different environments. More focussed research would help the situation. The present review highlights several areas of environmental antimony chemistry that urgently need to be addressed.Abstract. The objective of the present article is to present a critical overview of issues related to the current state of knowledge on the behaviour of antimony in the environment. It makes no attempt to systematically review all published data. However, it does provide a list of the main published reviews on antimony and identifies subjects where systematic reviews are needed. Areas where our knowledge is strong -and the corresponding gaps -in subjects ranging from total concentrations and speciation in the various environmental compartments, to ecotoxicity, to cycling between compartments, are discussed, along with the underlying research. Determining total antimony no longer poses a problem for most environmental samples but speciation measurements remain challenging throughout the process, from sampling to analysis. This means that the analytical tools still need to be improved but experience shows that, to be useful in practice, this should be directly driven by the requirements of laboratory and field measurements. Many different issues can be identified where further research is required, both in the laboratory and in the field, the most urgently needed studies probably being: (i) long-term spatial and temporal studies in the different environmental compartments in order to collect the data needed to establish a global biogeochemical cycle; (ii) laboratory studies of antimony interactions with potential natural binders; (iii) reliable ecotoxicological studies. Montserrat Filella is a chemist and teaches Environmental Chemistry at the University of Geneva, Switzerland. Her main research interests focus on the understanding of the physicochemical processes regulating the behaviour of chemical components in environmental and biological compartments, mainly by combining computer modelling with field and laboratory measurements. The three main axes of her research concern the study of: colloids in natural waters, natural organic matter (quantification and interaction with trace elements) and Group 15 elements. She is also interested in other topics

“…Ion-exchange [10] and chelating sorbents [11] and co-precipitation [12] can be pronounced as the most commonly used separation and preconcentration methods used in antimony determinations. Of all the methods for the determination of antimony in various samples, inductively coupled plasma mass spectrometry (ICP-MS) [13] and atomic absorption spectrometry (AAS) [14][15][16][17][18][19], especially after a hydride generation step, are the most useful and the sensitive techniques. Alternative applications using chromatographic [20], fluorimetric [21], and spectroscopic detection [22] systems can also be used.…”

“…Moreover, ICP-MS was the technique established by the EPA for the determination of contaminants (such as antimony) in drinking water [11]. Flame atomic absorption spectrometry (FAAS) and graphite furnace atomic absorption spectrometry (GFAAS) have been employed as well [1,[12][13][14][15][16].…”

“…Some interesting points need to be brought up when mentioning the GFAAS methods described in literature [1,[12][13][14][15][16]. Firstly, the background correction has been successfully carried out by means of deuterium lamps [1,16] or longitudinal Zeeman effect background correctors, with transversely heated graphite atomizers (THGA) [12][13][14][15].…”

Preliminary results of a quick, simple method of detecting antimony in water samples

Abstract:Preliminary results of development of a direct and fast method of determination of antimony in samples of tap water using GFAAS are presented. The found levels of antimony were lower than permitted for human consumption. A mixture of Pd and Mg(NO 3 ) 2 (concentrations in the injected solution: 8.6 µg mL -1 and 5.8 µg mL -1 respectively) was used as the chemical modifier. The pyrolysis and atomization temperatures were 1000 and 1700ºC, respectively and the mean analytical recovery 98.2%. Warsaw and Springer-Verlag Berlin Heidelberg. © Versita
