摘要：

In this work polypyrrole nanoparticles of high electrochemical activity were used to prepare disposable, potentiometric sensors with a paper support. The paper support modified with polypyrrole nanoparticles served as electrical lead and ion-to-electron transducer and it was covered by a typical poly(vinyl chloride) based ion-selective membrane. The properties of this arrangement were tested on example of potassium-selective electrodes. The sensors prepared benefited from the properties of conducting polymer nanostructures: high electrical conductivity and electroactivity as well as absence of suspension stabilizing agent. The obtained electrodes were characterized with analytical parameters well comparable with those of classical ion-selective electrodes.
