“…23 The resulting volatile fluorosilanes can be determined by gas chromatography following either liquid extraction with organic solvents or solid-phase microextraction from the headspace, achieving a detection limit of 6 µg/L in the latter case with Me 3 SiF. 21 However the Si-F bond in these derivatives is not stable in aqueous solutions, especially at high pH.…”

Gaseous fluoroethane was readily separated from the matrix, sampled from the headspace and determined by gas chromatography/mass spectrometry. The method was validated using rainwater certified reference material (IRMM CA408) and subsequently applied to the determination of fluoride in various matrices, including tap water, seawater, and urine. An instrumental limit of detection of 3.2 µg/L with a linear range up to 50 mg/L was achieved. The proposed derivatization is a one-step reaction, requires no organic solvents and is safe, as the derivatizing agent is nonvolatile. Determination of fluoride is affected by common fluoridecomplexing agents, such as Al(III) and Fe(III). The effect of large ...

“…21 Recently in our research group we have developed a HPLC method as mentioned above for the determination of TOF, based on the transformation of fluoride into TPSiF. 10 As this compound is volatile, although the separation requires a higher temperature than the earlier used trialkylfluorosilanes, 12,14 it can be also determined by the GC with various detection methods. The aim of this work was to develop a GC method for the determination of TOF with the use of the earlier developed defluorination procedure with SBP and derivatization of fluoride to TPSiF.…”

Abstract. Because of the global presence of anthropogenic perfluorinated organic compounds in the environment, foods and living organisms, and their large structural variety, it can be helpful to develop a method for determination of their total content at trace level in different matrices. In the developed method, the defluorination was carried with sodium biphenyl, derivatization of released fluoride to triphenylfluorosilane and determination by gas chromatography. Three detection methods were compared: flameionization detection, electron capture detection and mass spectrometry. Among them the MS detection was found to be the most favorable one in terms of the instrumental limit of detection (LOD) , whereas the flame-ionization detection was considered to be the most favorable in terms of the method limit of detection (MDL). For the initial sample volume of 1 L and performing the whole procedure of determination, including preconcentration, the MDL value for perfluorooctanoic acid was evaluated as 0.043 ppb.

“…There is no unified view on existing forms of fluoride in the Antarctic krill at home and abroad. The fluoride content can be determined by ISE ( Frant & Ross 1966;Čápka et al 2004;Xie et al 2012), spectrophotometry (Khalifa & Hafez 1998), gas chromatography (GC) (Chiba et al 1982;Haldimann & Zimmerli 1993), ion chromatography (IC) (Jeyakumar et al 2008;Koch et al 2010;Lefler & Ivey 2011), and high performance liquid chromatography (HPLC) (Lipka et al 2000;Musijowski et al 2010). IC has been chosen in this paper, as it is a rapid, selective, sensitive and preferred method for the determination of a variety of anions at trace and ultra-trace levels (Pereira 1992;Lopez-Ruiz 2000).…”

A rapid, sensitive and reliable method to quantify fluoride in Antarctic krill has been established. Four different pretreatment methods were used for the extraction of fluoride: double-deionised water extraction, sulphuric acid distillation, hydrochloric acid extraction, and pH adjustment with buffer after hydrochloric acid extraction. Four methods of comparative analysis revealed that sulphuric acid distillation was suitable preparation for ion chromatography determination of fluoride in Antarctic krill (fluoride content 288.7 ± 10.2 mg/kg). The method was partially validated in linearity, accuracy, and precision. The linear range was from 0.1 to 10.0 mg/l with the regression coefficient of 0.99998. The accuracy expressed as the recoveries of standard addition ranged from 95.3% to 101.3%, the relative standard deviation (n = 8) was 1.8-1.9%. With this method, the 3σ limit of detection was 0.06 mg/l of fluoride in Antarctic krill. Our results indicate that the method (limit of quantification 0.2 mg/l) could be well applied for the determination of fluoride in Antarctic krill.
