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 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...

Where E0 is the standard electrode potential, R is the universal gas constant, T is the absolute temperature, z is the number of moles of electrons transferred in the cell reaction or halfreaction, F is the Faraday-constant, and cox and cred are the concentrations of the oxidized and reduced forms of the component. The potential of the hydrogen electrode is declared to be 0.000 V at all tempera...
متن کاملDetermination of Fluoride in Various Samples and Some Infusions Using a Fluoride Selective Electrode
Introduction Fluoride (F−) is an important anion, present in various environmental, clinical and food samples. Small amounts of fluoride are vital for the human organism, but it is toxic in larger amounts. For adults the lethal dose is 0.20–0.35 g F− per kg body weight. Fluoride is widely used in various branches of industry and some fluoride compounds are formed as by-products in certain proce...
