This work presents a nano-Al 2 O 3 solid phase extraction technique for the determination of ultra-trace amounts of inorganic selenium species in aqueous systems using ion chromatography inductively coupled plasma-mass spectrometry (IC-ICP-MS). In this experiment, the inorganic selenium species were successfully extracted on a nano-Al 2 O 3 solid phase column and then quantitative eluted with a 100 mmol L -1 NaOH solution. Extraction conditions such as solvent identity, solvent concentration, solvent volume, solvent pH and salt addition were optimized. Under the optimum extraction conditions (elute solvent: 100 mmol L -1 NaOH, solvent volume: 4 mL, pH: 7.0), low detection limits (Se (IV): 6 ng L , R 2 > 0.999) were obtained for all of the analytes. Good spiked recoveries over the range of 80-98% were obtained by applying the proposed method on real environmental water samples. These results indicated that this method is very sensitive and reliable when monitoring trace levels of inorganic selenium species in aqueous samples. Sp. z o.o. © Versita

Recent Microextraction Techniques for Determination and Chemical Speciation of Selenium

Abstract:Research designed to improve extraction has led to the development of microextraction techniques (ME), which involve simple, low cost, and effective preconcentration of analytes in various matrices. This review is concerned with the principles and theoretical background of ME, as well as the development of applications for selenium analysis during the period from 2008 to 2016. Among all ME, dispersive liquid-liquid microextraction was found to be most favorable for selenium. On the other hand, atomic absorption spectrometry was the most frequently used instrumentation. Selenium ME have rarely been coupled to spectrophotometry and X-ray spectrophotometry methods, and there is no published application of ME with electrochemical techniques. We strongly support the idea of using a double preconcentration process, which consists of microextraction prior to preconcentration, followed by selenium determination using cathodic stripping voltammetry (ME-CSV). More attention should focus on the development of accurate, precise, and green methods for selenium analysis.

“…Although, conventional extraction methods can be obtaining reliable results, they usually have some disadvantages such as required long time, labor intensive and/or required large volumes of extracting solvent. In order to find a solution to pre-concentration, microextraction techniques, namely single drop microextraction (SDME) (Maltes et al 2008;Manzoori et al 2009), solid phase microextraction (SPME) (Zhang et al 1994;Górecki and Pawliszyn 1996;Djozan and Assadi 2004) dispersive liquid liquid microextraction (DLLME) (López-García et al 2014;Jalbani and Soylak 2015;Rosa et al 2015) and hollow fiber liquid phase microextraction (HFLPME) (Xia et al 2007;Jiang et al 2009;Saleh et al 2009) have been reported. Solidified of floating organic droplet microextraction (SFODME) was developed in 2007 (Lam et al 2010).…”

A rapid, inexpensive and practical solidified of floating organic droplet microextraction (SFODME) prior to electrothermal atomic absorption spectrometry (ETAAS) was proposed for lead (Pb) determination in herb samples. For SFODME procedure, 1-(2-pysidylazo)-2-naphthol was used as a complexing agent. Analytical parameters influencing the extraction efficiency, i.e. types and volume of extracting solvent, concentration of 1-(2-pyridylazo)-2-naphthol, pH, extraction temperature and time were optimized. Under the optimized conditions, LOD and LOQ were 0.064 and 0.214 µg L -1 , respectively, and an enrichment factor was achieved at 18.71 with the relative standard deviation ranging from 1.3 to 2.5% (n=6). The proposed method was effectively applied to the determination of lead in Spinach leaves (SRM-1570a) and Thai herb samples with acceptable results.
