Nowe możliwości zastosowań i testowania elektrod jonoselektywnych dzięki wykorzystaniu elektrochemicznych technik prądowych

Ion-selective electrodes are routine analytical tools used in industry, health care, environmental protection, etc. Over the decades, these sensors have been developed and optimized for applications in potentiometry. However, recent years have shown that the application of electrochemical current based techniques can bring significant benefits, both in terms of improving analytical parameters and extending the area of research on the basic properties of this class of sensors. Using the above-mentioned techniques, it is possible, among others, to lower the detection limit, increase sensitivity and signal stability. Moreover, due to controlled modification of the composition of ion-selective membranes by galvanostatic polarization, analytical parameters of sensors working in potentiometric mode can be improved. These methods also offer the possibility to examine charge transport in electrode membranes and at phase boundaries, and to study mechanism of ion sensors work.
