Theoretical consideration of tensammetric titration curves

Abstract

In the amperometric titrations in very dilute solutions, it is difficult and uncertain to obtain the equivalent point by the tangent method. It is desirable, therefore, to correct the experimental data by theoretical calculation.
In this paper, a general equation of the tensammetric titration curves for oxine-dilute metal ion systems is considered by taking into account the equilibrium conditions and the sensitivity limit of the measurement. The calculated titration curves agree well with the experimental results reported previously. The applicability of these theoretical corrections were di scussed for various metal ions.
