Determination of fluoride in wine by fluoride selective ion electrode, standard addition method: collaborative study.
The accuracy, precision, and reproducibility of a rapid method for determination of fluoride in wine, using a fluoride selective ion electrode, were established by a collaborative study involving 12 laboratories, 5 in Europe and 7 in the United States. The laboratories assayed 6 Youden pairs of fluoride-fortified, red and white wine samples with fluoride concentrations ranging from 0.2 to 3.0 m...
متن کاملDetermination of Fluoride and Some Metal Ion Levels in the Drinking Waters in Kayseri Province
Fluorine is one of the most common elements in the Earth’s crust. Fluoride is recognized to be the most effective caries-preventive agent. The main sources of fluoride for people are generally food and drinking water. For this reason, the fluoride and also the metal ion (Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, Pb and Zn) concentrations in the drinking waters collected from the city center of Kayseri...
متن کاملRapid method for the determination of trace fluoride and activation of ion-selective electrode.
A method for activating ISE is proposed that can allow determination of the fluoride concentration at ng mL(-1) level with good precision and accuracy. Fluoride ISE is activated in 0.5 mol L(-1) HClO4 medium and then fluoride is determined in the same medium. The linear range for the determination of fluoride is between 1.00 x 10(-2)-1.00 x 10(-7) mol L(-1), and the detection limit of the metho...
متن کاملDetermination of fluoride using ion-selective electrodes in the presence of aluminum.
We describe a method for determining fluoride with ion-selective electrodes (ISEs). Tartrate and Tris-based total ionic strength adjustment buffers (TISABs) were found to lower the interference from aluminum to a greater extent than conventional citrate-based TISABs. We adopted a solid TISAB addition method that is simple to perform, and can be carried out without lowering the level of fluoride...
متن کاملDetermination of chloride and fluoride in elemental boron using ion chromatography with suppressed conductivity detection
An accurate method based on combination of microwave assisted digestionsuppressed ion chromatography is proposed for the determination of fluoride and chloride in nuclear grade enriched boron (B10). The digestion of the boron matrix is carried out in closed vessel microwave assisted digestion using hydrogen peroxide and dilute nitric acid. By using the microwave assisted approach, the digestion...
