“…In principle, there is a number of conventional techniques capable of determination of highly electronegative nonmetals in a liquid phase, including spectrometry (Wang & Wolfbeis, 2014), the use of CNO‐analysers (Kirsten, 1983), Winkler's titration (Bondyale‐Juez et al, 2017; Shriwastav et al, 2017), pyrohydrolysis (Banks, Burke, & O'Laughlin, 1958; Shekhar et al, 2003), ion chromatography (Kapinus et al, 2004; Sawant et al, 2007; Zhang et al, 2012; Mukai et al, 2019; Wang et al, 2020), high‐performance liquid chromatography (Xu et al, 2004), and electrochemical approaches (ion‐selective electrodes and voltammetry) (Lupo et al, 2012; Mao et al, 2013; Bektas et al, 2018). In the case of analyzing solids, those techniques are limited by the aforementioned dissolution problems.…”

The determination of nonmetals, first of all, the most electronegative ones—nitrogen, oxygen, fluorine, chlorine, and bromine, poses the highest challenge for element analysis. These elements are characterized by high reactivity, volatility, high ionization energy, and the absence of intensive spectral lines in the optical spectral range. Conventional techniques of their quantification include considerable “wet chemistry” stages so the application of these techniques for the solid sample is highly laborious and prone to uncontrollable uncertainties. Additionally, current development in material science and other areas requires the quantification of the elements at lower levels with good sensitivity. Owing to their robustness and flexibility, mass spectrometry techniques provide vast possibilities for the quantification, spatial and isotopic analysis, including the solutions for direct analysis of solids. The current review focuses on the application of major mass spectrometric techniques for the quantification of N, O, F, Cl, and Br in solid samples. The following techniques are mainly considered: thermal ionization mass spectrometry (TIMS), isotope‐ratio MS (IRMS), secondary ion MS (SIMS), inductively coupled plasma MS (ICP‐MS), and glow discharge MS (GDMS); as the most accessible and widely applied for the purpose. General ionization issues, advantages, limitations, and novel methodological solutions are discussed. © 2020 John Wiley & Sons Ltd.

“…For fluoride ion (F − ), the smallest size and highest charge density, any chronic deficiency of F − will lead to gastric and kidney disorder or osteoporosis, while excess F − would induce dental and skeletal fluorosis and other serious diseases including collagen breakdown, bone disorders and immune system disruption . Great efforts have been devoted for F − detection, such as chromatography, electrochemistry, photoluminescence, mass spectrometry,, fluorescent spectrophotometry and colorimetric spectrophotometry . For example, Bhosale, et al .…”

An improved D−A‐D typed π‐conjugated optical chromophore (PBHPI) with multi‐activated recognition sites and its functionalized testing‐paper strips were constructed and developed, for the first time, based on B3LYP/6‐31G level of theory in Gaussian 03 suite. After its UV‐vis spectral property was investigated in detail, it was noted to find that the target PBHPI and its functionalized paper strips could conclusively react with F− with obvious color change from light yellow to dark red. Under the optimized experimental conditions, both PBHPI and its functionalized paper‐strips could selectively recognize F− with a double‐wavelength colorimetric response to realize a wide linear range from 5.0 ×10–6 mol/L to 1.4 ×10–4 mol/L. The present sensing systems were successfully applied for visually on‐site monitoring F− in some commercial organic and toothpaste samples simply and conveniently. The recognition mechanism was confirmed to be the deprotonating mechanism to form multiple hydrogen bonds as what we expected.

“…The determination of fluoride in water samples is usually performed using chromatographic methods, such as ion chromatography (IC) [ 6 ], gas chromatography (GC) [ 7 ] and high-performance liquid chromatography (HPLC) [ 8 , 9 ] or electrochemical methods, such as ion selective electrodes (ISE) [ 10 , 11 ], polarography [ 12 ] and voltammetry [ 13 ]. Spectroscopic methods, for example inductively coupled plasma-optical emission spectrometry (ICP-OES) or classical atomic absorption spectrometry (AAS), are not used for determination of F because of the very high ionisation potential (17.42 eV) and the resonance lines of the fluorine being below 100 nm.…”

This work presents ultrasound-assisted dispersive micro solid phase extraction (USA DMSPE) for preconcentration of fluorine (F) in water and herb samples. TiO2 nanoparticles (NPs) were used as an adsorbent. The determination with slurry sampling was performed via molecular absorption of calcium monofluoride (CaF) at 606.440 nm using a high-resolution continuum source electrothermal absorption spectrometry (HR-CS ET MAS). Several factors influencing the efficiency of the preconcentration technique, such as the amount of TiO2, pH of sample solution, ultrasonication and centrifugation time and TiO2 slurry solution preparation before injection to HR-CS ET MAS, were investigated in detail. The conditions of detection step (wavelength, calcium amount, pyrolysis and molecule-forming temperatures) were also studied. After extraction, adsorbent with the analyte was mixed with 200 μL of H2O to prepare a slurry solution. The concentration limit of detection was 0.13 ng mL−1. The achieved preconcentration factor was 7. The relative standard deviations (RSDs, %) for F in real samples were 3–15%. The accuracy of this method was evaluated by analyses of certified reference materials after spiking: INCT-MPH-2 (Mixed Polish Herbs), INCT-SBF-4 (Soya Bean Flour), ERM-CAO11b (Hard Drinking Water) and TMDA-54.5 (Lake Ontario Water). The measured F contents in reference materials were in satisfactory agreement with the added amounts, and the recoveries were found to be 97–109%. Under the developed extraction conditions, the proposed method has been successfully applied for the determination of F in real water samples (lake, sea, tap water) and herbs.
