摘要：

A simple and reproducible method for mass production of disposable, plastic, thick-film, ion-selective electrodes using screen-printing technology is described. The properties of selective sensors for potassium, ammonium and nitrate ions obtained with this technology are shown and discussed. All the obtained strip sensors have analytical characteristics (sensitivity, selectivity, dynamic range and response time) comparable with those for conventional ion-selective electrodes. However, they practically do not require any conditioning before measurements and they respond in short time (steady-state signal is reached after a few seconds), that is important in case of the disposable sensors.
