PYROLYZED PHOTORESIST FILM ELECTRODES FOR APPLICATION IN ELECTROANALYSIS

Vlastimil Řeáček – Ivan Hotový – Marian Vojs – Mário Kotlár – Thomas Kups – Lothar Spiess

   Pyrolyzed photoresist film (PPF) electrodes for application in electroanalysis were prepared on alumina substrates. These electrodes were characterized for their electrical, microstructural (by Raman spectroscopy) and electrochemical properties. As a support, the PPF electrodes were tested for simultaneous determination of Pb(II), Cd(II) and Zn(II) in an aqueous solution on in-situ formed bismuth film by square wave voltammetry (SWV). The dependence of the stripping responses on the concentration of target metals was linear in the range from 1·10-8 to 9·10-8 mol/L. The effect of activation of the PPF surface by argon plasma on analytical performance of bismuth film electrode (BiFE) on PPF support was also investigated.

Keywords: pyrolyzed photoresist film, Bismuth film electrode, anodic stripping voltammetry
