Ion-selective electrode potentiometry
Did you know?
WebPotentiometry is an electrochemical method in which the potential of an electrochemical cell is measured while little to no current is passed through the sample. In titrimetric methods, this measurement can be used to indicate the end point. WebNOTE : This method is for the analysis of simple fluoride ion rather than total fluoride, a s analysis 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 …
WebThis selectivity provides potentiometric electrodes with a significant advantage over other quantitative methods of analysis if we need to determine the concentration of free ions. For example, calcium is present in urine both as free Ca 2 + ions and as protein-bound Ca 2 … The Analyte May Participate in Other Reactions. Figure 11.2 shows how the elect… Note.
