Abstract

The electrode response characteristics in flow injection of a recently described polymer membrane potentiometric sensor for silver are investigated. This was accomplished by carrying out a 24-hour electrode response monitoring on the silver sensor under continuous flow conditions. At longer periods (>2 hours) a deterioration in the sensor response started to manifest itself. Response time studies showed that there was lost in sensitivity as seen as a shift in the baseline potential. These phenomena were attributed to factors such as loss of active components of the membrane (plasticiser) and the uptake of water by the sensor membrane.
