“…Samples only need to be filtered before being analyzed without any other pretreatment such as dilution. This fact constitutes a valuable advantage over other methods such as ion chromatography [19] since the high amount of chloride in seawater normally masks the determination of other ions. The electrochemical reduction of the chloride concentration without influencing the concentration of the remainder of the ions is especially attractive.…”

Chemical speciation is a very important subject in the environmental protection, toxicology, and chemical analytics due to the fact that toxicity, availability, and reactivity of trace elements depend on the chemical forms in which these elements occur. Research on low analyte levels, particularly in complex matrix samples, requires more and more advanced and sophisticated analytical methods and techniques. The latest trends in this field concern the so-called hyphenated techniques. Arsenic, antimony, chromium, and (underestimated) thallium attract the closest attention of toxicologists and analysts. The properties of those elements depend on the oxidation state in which they occur. The aim of the following paper is to answer the question why the speciation analytics is so important. The paper also provides numerous examples of the hyphenated technique usage (e.g., the LC-ICP-MS application in the speciation analysis of chromium, antimony, arsenic, or thallium in water and bottom sediment samples). An important issue addressed is the preparation of environmental samples for speciation analysis.

“…Important limitations of these techniques are that only Sb species that can undergo chemical reduction can be determined, and that Sb(III) is unstable and easily oxidized to Sb(V), hence many research papers report relatively high Sb(V) content in the analyzed samples. [21] For this reason, hyphenated techniques have been proposed to attain direct speciation of Sb.…”

“…A hyphenated technique, high-performance liquid chromatography (LC) with an inductively coupled plasma-mass spectrometry (ICP-MS), is commonly employed for the separation and detection of Sb species. [21][22][23][24][25] LC-ICP-MS has been applied to environmental samples including sediments and water (sea, surface, canal and tap water).…”

A method for the analysis of different species of antimony (Sb) that couples liquid chromatography with an inductively coupled plasma-optical emission spectrometry (LC-ICP-OES) system is presented. The method is simple and reliable to separate and quantify directly and simultaneously Sb(III) and Sb(V) in aqueous samples. The calibration curves showed high linearity at the three wavelengths tested. The limits of detection ranged from 24.9 to 32.3 μg/L for Sb(III) and from 36.2 to 46.0 μg/L for Sb(V), at the three wavelengths evaluated. The limit of detection for this method varied depending on the wavelength used. The lowest limit of quantification for Sb(V) (49.9 μg/L) and Sb(III) (80.7 μg/L) was obtained at a wavelength of 217.582 nm. The method sensitivity for Sb(V) was higher compared to Sb(III) at all the wavelengths considered. Samples containing different concentrations of Sb(III) and Sb(V) in three different matrices, i.e., water, basal culture medium, and anaerobic sludge plus basal medium, were analyzed. The coefficients of variation were low and ranged from 0.1 to 5.0 depending on the sample matrix. Recoveries of Sb(III) and Sb(V) were higher than 90% independently of the matrix analyzed and the wavelength used in the analysis.
