摘要：

Plastic, fully screen-printed, disposable pH sensors based on ruthenium dioxide are described. Application of thick-film technology results in highly reproducible fabrication of the sensors. The electrodes enable fast measurements, with good sensitivity (51 mV/pH), in acidic and neutral solutions (linear range of response up to pH=8). No interferences from all;aline cations, commonly accompanying anions and complexing ligands were observed. The pH measurements were strongly affected by reducing substances. Some potential analytical applications of the sensors are pointed. (C) 1997 Elsevier Science B.V.
