“…Molecular absorption spectrometry with graphite furnace solid sampling was also suggested for halogen quantification based on molecular spectra of halogen‐metal compounds (de Moraes Flores et al, 2007; Bücker, Hoffmann, & Acker, 2014; Pereira et al, 2014; Pereira et al, 2015; Cadorim et al, 2018; MacHado et al, 2020). However, such indirect measurements may suffer from potential interferences and increased uncertainties compared to the use of conventional atomic spectra.Nuclear techniques are also worth noting in respect of quantification of highly electronegative nonmetals (neutron activation analysis and proton‐induced gamma‐ray, particle‐induced gamma emission) (Cohen & Rose 1992; Landsberger, Basunia, & Iskander, 2001; Shekhar et al, 2003; Muñoz et al, 2009; Funato et al, 2015; Heckel et al, 2016; Kumar et al, 2016; Dhorge et al, 2017). Nuclear techniques provide the lowest LoD values for the elements (e.g., LoD ca.…”

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.

“…Dental fluorosis has been linked to fluoride levels between 1.5 and 4 mg L -1 (Salah and Arab 2007). Skeletal fluorosis develops with sustained exposure to greater concentrations of fluorine sewage (4 to 10 mg L -1 ) (Raja Reddy 2009;Dhorge et al 2017). Thus, eliminating F-containing materials to reduce environmental concerns and using silicon-containing materials incorporated into alkylbased polymer materials to promote hydrophobicity have become a research hotspot in recent years (Tang et al 2015(Tang et al , 2016Lin et al 2019).…”

Hydrophobic materials have promising applications. However, fluorine present in hydrophobic materials can lead to health risks and environmental pollution. This study investigated an environmentally friendly route to produce fluorine-free hydrophobic coatings with good wear resistance. Wear-resistant hydrophobic coatings were prepared by introducing different ratios of spirocyclic alkoxysilane into the epoxy resin. Characterization by Fourier transform infrared spectroscopy, water contact angle measurement, scanning electron microscope, tape adhesion test, and abrasion testing showed that the multi-methyl group and double-ring rigid skeleton structure of spirocyclic alkoxysilane can remarkably improve the hydrophobic performance and wear resistance of the epoxy resin. The modified hydrophobic coatings can withstand more than 1600 instances of controlled rubbing. Furthermore, the maximum water contact angle can reach 110° after substantial abrasion. The novelty of the work is that the authors successfully synthesized spirocyclic alkoxysilane for the first-time using corn straw ash. The prepared spirocyclic alkoxysilane was then used as a modifier to prepare hydrophobic epoxy resin coating. This approach can broaden the utilization of corn straw ash. Therefore, this method can achieve a green and low-cost preparation of wear-resistant hydrophobic coatings without the introduction of fluorine.

“…16 Conventional PIGE has been utilized for the characterization of coal, soil, sediment, and forensic samples. 15,17–19 To further obtain a simple and rapid analytical method, as required, an external (in air) PIGE method has been utilized in our laboratory. 5 It was found to reduce the turnaround time of analysis without any vacuum requirements, where the sample was exposed to the extracted proton beam in air.…”
