Abstract

The analytical performances of ionophore based potassium and calcium sensitive membranes were tested under current control or following a DC current pretreatment. The effects of the direction and magnitude of the applied current were evaluated on the response slopes, the detection limits and selectivity coefficients. The results are discussed in the light of expectations and the theoretical and practical difficulties.
