Original Abstract

This paper deals with the problem of the replacement of mercury drop electrodes with solid electrodes in standard polarography. The screen-printed thick-film sensor with a three-electrode system was prepared. A working electrode was modified with nanopatterned nanostructures. Vertically aligned carbon nanotubes (CNTs) were grown on the working electrode. The process of the nanotubes growing was tested to create a homogeneous (CNTs) and high density CNT layer directly on the thick-film silver (Ag) layer. Thereby, the modified electrode is presented to be very perspective in heavy metal detection using electrochemical methods because of improvement of detection properties. The authors were able to determine the concentration of cadmium ions in units of umol/L.
