“…In our previous works, the four arsenic species were completely separated by conventional column (Lee et al 2019;Son et al 2019;Nam et al 2016). The lower resolving power of the capillary column used in this work could be attributed to its smaller inner diameter (0.4 mm) and particle size (4 μm) as compared to the conventional column (inner diameter = 4.6 mm and particle size = 10 μm).…”

The toxicity and biological activity of arsenic depend on its chemical form. In particular, inorganic arsenics are more toxic than organic ones. Apart from the determination of total arsenics, their accurate speciation is important for toxicity assessment. To separate arsenic species using a cation or an anion separation column, at least 0.5–1.0 mL of sample is required because conventional ion chromatography columns use a sample loop of 100–200 μL. It is thus difficult to analyze samples with small volumes, such as clinical and biological samples. In this study, a method for separating arsenic species using a 5-μL sample loop combined with a capillary ion exchange column has been developed for analyzing small volume of samples. The separated arsenics were determined by inductively coupled plasma mass spectrometry. By oxidizing As(III) to As(V) prior to analysis, the total inorganic arsenics, As(III) and As(V), could be well separated from the organic ones. Linear calibration curves (0.5–50 μg/kg) were obtained for total inorganic arsenics dissolved in water. Sub-picogram-level detection limit was obtained. The analytical capability of this method was successfully validated for certified reference materials, namely water and human urine, with total inorganic arsenic recovery efficiencies of 100% and 121%, respectively. Our method requires less than ~ 10 μL of sample and will be very useful to analyze valuable samples available in limited amounts.

“…The sample loop volume for conventional chromatography column is generally more than 100-200 μL (Son et al 2019;Rosa et al 2019;Nogueira et al 2018). The amount of sample required for analysis using this sample loop is typically 0.5-1.0 mL or more.…”

“…There are many analytical methods available for monitoring metal ions, including atomic absorption spectrometry [14,15], inductively coupled plasma mass spectrometry [16], and anodic stripping voltammetry [17]. Compared with the above detection methods, fluorescence analysis has gradually become an effective tool in the field of analysis and detection, not only due to its advantages of high sensitivity, as well as low detection limit, but also owing to its visual recognition and low intracellular toxicity [18][19][20][21][22][23][24][25][26][27][28][29].…”

An easy prepared probe, BHMMP, was designed and synthesized, which displayed a significant fluorescence enhancement (over 38-fold) and obvious color change in the recognition of Al3+. The binding ratio of probe BHMMP to Al3+ was determined as 1:1, according to Job plot. The binding mechanism was fully clarified by the experiments, such as FT-IR spectrum, ESI–MS analysis, and 1H NMR titration. A DFT study further confirmed the binding mode of BHMMP to Al3+. The limit of detection (LOD) for Al3+ was determined as low as 0.70 µM, based on the fluorescence titration of BHMMP. Moreover, the results from real sample experiments, including real water samples, test papers, and cell images, well-demonstrated that BHMMP was capable of sensing Al3+ in environmental and biological systems.

“…Different analytical procedure used for arsenic determination of speciation/determination in water samples. A few of them only determination without speciation such as graphite furnace atomic absorption spectrometry (GF-AAS) [8], Flame atomic absorption spectrometry (F-AAS) [9], hydride generation atomic absorption spectrometry (HG-AAS) [10], capillary electrophoresis with inductively coupled plasma-mass spectrometry (CE-ICP) [11] and arsenic species can be determined with ion chromatography coupled to inductively coupled plasma mass spectrometry (IC-ICP-MS) [12]. As low concentration of arsenic species in waters (sub ppb), sample preparation must be used before instrumental analysis.…”

A simple and applied method based on O-3-Tert-butylphenyl N-(6-methoxy-2-pyridyl)-N-methylthiocarbamate (Pyributicarbamate; TBMPMTC) was used for arsenic speciation (AsIII and AsV) in urine and water samples by dispersive liquid-liquid microextraction (DLLME) procedure. The concentrations of arsenic in the liquid phase were determined by hydride generation atomic absorption spectrometry in the presence of flame accessory (HG-AAS). By procedure, a mixture of ionic liquid (0.1 g, [APMIM][PF6]@[HMIM][PF6]), acetone (0.2 mL) and pyributicarbamate was injected into wastewater sample containing arsenic (AsIII and AsV) ions, which were already extracted by pyributicarbamate at the optimized pH. The task-specific ionic liquid (TSIL) of 1-3-aminopropyl)-3-methyl-imidazoliumhexafluorophosphate [APMIM][PF6] was chemically synthesized and used for increasing of As(V) extraction in the liquid phase. As(III) was extracted based on the sulfur bond of pyributicarbamate at pH=5.3. As (V) can be extracted by amine group of TBMPMTC and [APMIM][PF6] at pH=3.0 (As(V) --- : NH2). The influence of parameters was studied.
