Determination of Aluminum in Dialysis Concentrates by Atomic Absorption Spectrometry after Coprecipitation with Lanthanum Phosphate
This method was developed for the determination of trace amounts of aluminum(III) in dialysis concentrates using atomic absorption spectrometry after coprecipitation with lanthanum phosfate. The analytical parameters that influenced the quantitave coprecipitation of analyte including amount of lanthanum, amount of phosfate, pH and duration time were optimized. The % recoveries of the analyte io...

متن کاملMeasurements with fluoride ion selective electrode
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 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...
