ELECTROCHEMICAL IMPEDANCE CHARACTERIZATION OF POLY{N,N′-ETHYLENEBIS[N-[(3-(PYRROLE-1-YL)PROPYL) CARBAMOYL)METHYL]-GLYCINE]} MODIFIED ELECTRODES. Authors: . |

Abstract: Glassy carbon disk electrodes modified with film of poly N,N′-ethylenebis[N-[(3-(pyrrole-1-yl)propyl)carbamoyl)methyl]-glycine] (polyL) have been studied by electrochemical impedance spectroscopy (EIS) in order to get a better understanding of their complexing properties towards metal ions. Investigation of the EIS equivalent circuit clearly demonstrated that the morphological structure of the polyL depends on the film thickness and of the complexing species (ions of Hg2+, Cu2+ or Pb2+) and their oxidation state as well. Keywords: Poly(N,N′-ethylenebis[N-[(3-(pyrrole-1-yl)propyl) carbamoyl)methyl]-glycine]) films; Modified electrodes; Electrochemical Impedance Spectroscopy. |
