Ionic liquid based carrier mediated hollow fiber liquid liquid liquid microextraction combined with HPLC-ICP-MS for the speciation of phenylarsenic compounds in chicken and feed samples

Abstract

A novel method of ionic liquid based carrier mediated hollow fiber liquid liquid liquid microextraction (ILcarrier mediated HF-LLLME) combined with high performance liquid chromatography-inductively coupled plasma mass spectrometry (HPLC-ICP-MS) has been developed for the speciation of five phenylarsenic compounds and arsenate in chicken and feed samples. The target arsenic species were extracted from 6 mL aqueous samplesimpregnated in the pores of a hollow fiber, then back extracted into a 10 mL acceptor phase of 0.3 mol L À1 NaBr in the lumen of the hollow fiber. The main driving force for the extraction was the gradient concentration of the counter ion from the donor phase to the acceptor phase. Factors affecting the extraction of the target arsenic species were investigated in detail. Under the optimal conditions, the limits of detection (LODs, 3s) for five target phenylarsenic compounds and arsenate were in the range of 1.4-16.0 ng L À1 with the relative standard deviations (C As(V),4-OH,3-NHPAA,PA,4-NPAA ¼ 0.05 mg L À1 , C p-ASA ¼ 0.10 mg L À1 , n ¼ 7) ranging from 3.6 to 10.0%, and the enrichment factors were varied from 86 to 372-fold. The proposed method of IL-carrier mediated HF-LLLME-HPLC-ICP-MS was successfully applied to the determination of five phenylarsenic compounds and arsenate in chicken and feed samples with the recoveries of 79.2-105.4% and 81.1-117.8% for the spiked chicken and spiked feed samples, respectively.

Organoarsenicals in poultry litter: Detection, fate, and toxicity

“…For aqueous samples, a number of methods, such as solid-phase extraction (SPE) (Roerdink and Aldstadt, 2005;Vogel, 2005;Baert et al, 2006;Huff et al, 2007;Jaafar et al, 2007;Chen et al, 2011), solidphase microextraction (Roerdink and Aldstadt, 2004), and liquidphase extraction (Li and Hu, 2011;Wang et al, 2011;Guo et al, 2013), are utilized to eliminate matrix effects and concentrate organoarsenicals. SPE is the most widely used sample preparation method.…”

Green synthesis of surface-passivated carbon dots from the prickly pear cactus as a fluorescent probe for the dual detection of arsenic(iii) and hypochlorite ions from drinking water

“…Trace levels of As 3+ ions have been quantitatively detected by inductively coupled plasma mass spectroscopy (ICP-MS), inductively coupled plasma atomic emission spectrometry (ICP-AES), atomic uorescence spectrometry (AFS), and atomic absorption spectrometry (AAS). [21][22][23][24][25] The common analytical methods used for the accurate detection of As 3+ /ClO À ions are chemosensors, biosensors, and iodometric and polarographic methods. [26][27][28][29][30][31][32][33][34] Though these techniques are very qualitative and quantitative, yet they are limited to expensive instrumentation, inconvenient analytical methods, tedious material preparation procedures, and are time consuming.…”

Fast extraction methodologies for the determination of toxic arsenic in meat

“…Moreover, low levels of As species require low limits of detection on the determination method thus high sensitivity techniques. Analytical methods recently employed in arsenic speciation in meat samples involve traditional liquid–liquid extraction (Conklin et al ., ), ultrasounds extraction (Monasterio et al ., ; Batista et al ., ; Guo et al ., ; Liu et al ., ), accelerated solvent extraction (Cui et al ., ) and microwave‐assisted extraction (Zhang et al ., ), in combination with chromatographic separation of species. Liquid chromatography coupled to HG‐AFS (Monasterio et al ., ; Cui et al ., ) and mostly inductively coupled plasma mass spectrometry (ICP‐MS) (Fontcuberta et al ., ; Mao et al ., ; Yang et al ., ; Batista et al ., ; Guo et al ., ; Peng et al ., ; Zhang et al ., ; Liu et al ., ) and ion chromatography coupled to ICP‐MS (Conklin et al ., ), and capillary electrophoresis coupled to ICP‐MS (Liu et al ., ) have been employed for As speciation.…”
