On-line Measurement of the Concentration of Chloric Ion in the Electrolytic Solution
|
Abstract:
The relationship of the peak voltage Ep which AgCl electrode responds to Cl? with logarithm of Cl? concentration is linear in the pulse magnetic field, and the relationship between Ep and lgc(Cl?) is linear in the range of 10?4~10?1 mol/L. The linear range is close to conventional potentiometry. On-line measurement of Cl? concentration with ion-selective electrode in the transient pulse magnetic field. The ion transient state can be traced by measuring Ep in pulse magnetic field. This method has the advantages over conventional potentiometry in reproducibility and accuracy. The concentration of chloric ion in the electrolytic solution has been measured by the method, and measurement error is less than 6%.
