Abstract: Complexing polymer-coated electrodes synthesized by oxidative electropolymerization of N,N'-ethylenebis[N-[(3-(pyrrole-1-yl)propyl) carbamoyl)methyl]-glycine] (L) were used for the electrochemical detection of Hg(II) ions by means of the chemical pre-concentration-anodic stripping technique. Competitive complexations of Hg(II) and Cu(II) or Hg(II) and Pb(II) into C/polylL modified electrodes of different film thicknesses were carried out using increasing pre-concentration times. Optimized conditions for mercury ions analysis with polyL films were established upon varying experimental parameters such as pH, reduction potential, and accumulation and reduction times. Imprinted polymer-coated electrodes prepared by electropolymerization of L in the presence of metal cations were used for mercury sensing
