“…All glassware was previously soaked in 14% HNO 3 (V/V) and rinsed with de-ionised water before use. The analysis of V and Fe in extractants were performed with ICP-MS (Agilent 7500ce, Japan) by monitoring 51 V and using He collision cell to eliminate the ClO + interference (D'Ilio et al, 2011;Rousis et al, 2014) and ICP-OES (Vista-Pro radial, Varian, Germany). Total V in soils were quantified with X-ray fluorescence spectrometry (XRF, Spectro-X-Lab 2000, Germany).…”

Reviewing the current state of knowledge about sequential extraction applied for soil vanadium (V) fractionation, we identified an urgent requirement of an sequential extraction (SE) specified for V. Namely, almost all previous SE extracted only 8.4%-48% of total V in soils (excluding residue). Thus, we proposed an eight-step SE for V fractionation in soils according to the knowledge gained from literature and our own dissolution experiments with model minerals. After extracting the mobilisable and adsorbed V with de-ionised water and 5mmol/L phosphate, 1mol/L pyrophosphate was applied to gather organic matter bound V which minimised the artefact dissolving Al and Fe (hydr)oxides occurred when using HNO-HO for extraction. Extraction with 0.4mol/L NHOH⋅HCl was highly selective toward manganese oxides. Fractionation of different crystalline Al and Fe (hydr)oxides associated V with 1mol/L HCl, 0.2mol/L oxalate buffer and 4mol/L HCl at 95°C especially improved the extractability of V incorporated with crystalline phase associated V. The suitability of our new SE scheme was confirmed by its higher selectivity against the target phases and higher extraction efficiencies (55%-77% of total V) with model minerals and 6 soils of different properties than previous SE.

“…Atomic absorption spectrometric techniques are widely used in many disciplines for the analysis of foodstuffs, environmental samples, water, nanomaterials, pharmaceuticals and biological specimens. [1][2][3][4][5][6][7][8] The selection of the most appropriate technique for a specific analysis depends on many factors, such as sample type and composition, chemical nature of elements, multi-element and isotopic capability of the instrument, desired limits of detection (LODs), available instrumentation and cost of analysis. [9][10][11][12] Atomic absorption spectrometry (AAS) is one of the most used techniques for elemental analysis and is selected based on three different atomization processes: Flame AAS (FAAS), electrothermal AAS (ETAAS) or graphite furnace AAS (GFAAS), and chemical vapor generation AAS.…”

Electrothermal or graphite furnace atomic absorption spectrometry (ETAAS or GFAAS) is one of the most widely used techniques for determining elements in different matrices (e.g., foodstuffs, pharmaceuticals, biological specimens, nanomaterials, polymers, fuels and environmental media). Numerous elements can be simply and quickly determined with high precision and accuracy, low detection limits, and at moderate cost. The technique is also suitable for direct solid and slurry sample analysis. A crucial feature of this technique is that it can perform simultaneous or sequential multi-element analysis. Over the years, many instruments have come on the market for multi-elemental analysis using mostly line source (LS) GFAAS and high-resolution continuum source (HR-CS) GFAAS. This review covers publications from 2000 to 2020related to the simultaneous or sequential multi-elemental analysis by LS-GFAAS and HR-CS-GFAAS. Mainly the applications, the limits of detection, the use of internal standardization and other aspects regarding the matrix, pyrolysis and atomization temperatures and modifiers are discussed. Finally, a critical comparison is made between the LS-GFAAS and HR-CS-GFAAS techniques.

“…7,8 Spectral overlaps caused by atomic or polyatomic species with similar mass/charge ratios of the analytes are, however, the most serious interference in ICP-MS. Spectral interference is associated with either the argon plasma itself, components of the sample matrix, including the solvent, isotope overlaps, and oxygen or nitrogen gases from the surrounding air. 13 Chrastný et al evaluated the mixtures of He/NH 3 and He/H 2 for reducing chloride interference on V determination.

“…Based on the kinetic energy discrimination (KED) technology, H 2 and He were used as the cell gas and effectively attenuated polyatomic interferences on, among other elements, As, Cr and V determination. 13 Chrastný et al evaluated the mixtures of He/NH 3 and He/H 2 for reducing chloride interference on V determination. According to the authors, the He/H 2 mixture associated with KED technology sufficed to eliminate 35 Cl 16 O + interference on V determination in matrices containing up to 0.1 mol L À1 Cl À .…”

A novel strategy to determine As, Cr, Hg and V in drinking water by ICP-MS/MS

et al. 2015

This work demonstrates the potential of inductively coupled plasma tandem mass spectrometry (ICP-MS/MS) in trace element analysis. Aiming Hg determination in water, sample preservation requires chloride addition, which presents formation of polyatomic interfering ions as a drawback for the determination of other analytes (e.g. As and V). Thus, the effect of chloride on As, Cr, V and Hg determination and the feasibility of using ICP-MS/MS to circumvent the interference were evaluated. A standard reference material (NIST SRM 1643e) and recoveries from tap water spiked with As, Cr, Hg and V were used for accuracy assessment and for the evaluation of matrix effects. The reaction between Hg and oxygen gas is not favorable in the octopole reaction system (ORS 3 ). Therefore, Hg was accurately determined as a single atom ion ( 202 Hg + ) under the same analytical conditions adopted for As, Cr and V determination by monitoring 75 As 16 O + , 52 Cr 16 O + and 51 V 16 O + while the ORS 3 was pressurized with oxygen gas. The oxygen reaction mode significantly improved the accuracy for As, Cr and V, especially at the lowest spiked level, which is strongly affected by matrix effects. The signal gain in m/z 75 for a solution containing 1 mg L À1 As in 0.48 mol L À1 chloride medium was 1974% when employing single quadrupole mode. On the other hand, the signal increased only 7% when 0.75 mL min À1 O 2 was used in mass shift mode proving the efficiency of the MS/MS mode. Thus, ICP-MS/MS and ORS 3 pressurized with O 2 gas effectively reduced the interference, and enhanced the accuracy and sensitivity for some specific isotopes in a complex medium. The limits of detection for V ( 51 V 16 O + ), Cr ( 52 Cr 16 O + ), As ( 75 As 16 O + ) and Hg ( 202 Hg + ) were estimated to be 2, 3, 1.6 and 38 ng L À1 at the 99.7% confidence level, respectively.
