Abstract: | A simple, low-cost and reproducible method for the mass production of potentiometric ion-selective electrodes for copper
ions is presented. These planar, strip sensors were obtained by screen-printing. The application of pastes cured at low temperature
allows printing of the sensors on low-cost, plastic substrates. The pastes for printing of ion-sensitive thick-film membranes
were based on copper (I) and copper (II) sulfides. The analytical characteristics of the thick-film electrodes were compared.
The analytical properties (range of determination, sensitivity, selectivity, response time) of the copper (I) sulfide-based
sensors were comparable with those for conventional ion-selective electrodes.
