Abstract

The application field of potentiometry has been broadened by the appearance of new ion selective electrodes. Besides frequent laboratory use, these selective potentiometric sensors have also been applied to continuous monitoring and process control (1-4). If ion selective electrodes are used for these purposes, direct potentiometry is employed— in most cases—as a measuring method because of its simplicity. However, the potentiometric direct ion activity determination has several disadvantages, e.g., the need of frequent calibration, the relatively poor precision etc, which can be overcome to some extent with the potentiometric titration technique. As a matter of fact, the classical potentiometric titration technique is suitable only for analysis in individual samples, and it requires a rather sophisticated automatic sampler-titrator system to make it suitable for continuous monitoring.
