Ion selective electrode calibration curve
Webanalysis using the ion-selective electrode is not preceded by a distillation step. 1.2 The method detection limit is 0.5 mg/L. Fluoride concentrations from 0.025 to 500 mg/L ma y be measured. However, using a linear calibration, results less than 0.5 mg/L may b e biased up to approximately 160% high. WebIonic chromatography was chosen as the comparison method. Sensors made it possible to determine from 0.1 μM to10 mMiodide and bromide ions in mixtures. The proposed …

Effect of content of t-ZrO2 and plasticizer on the performance … WebAn Ion Selective Electrode measures the potential of a specific ion in solution. (The pH electrode is an ISE for the Hydrogen ion.) This potential is measured against a stable reference electrode of constant potential. The potential difference between the two electrodes will depend upon the activity of the specific ion in solution.
