Electrochemical studies and applications of tris[5-amino-1,10-phenanthroline]Fe[II] polymeric-film-coated glassy-carbon electrodes
The electrochemical polymerization and characterization of a polymeric film prepared by cyclic voltammetry of tris[5-amino-1,10-phenanthroline] iron[II] complex were performed using UV-visible, infrared spectra and electron scanning microscopy. Counter-ion effects were evaluated by cyclic voltammetry and by detection of NO[sub 2](g). Modified electrodes of the type studied were applied as amperometric detectors. The determination of NO[sub 2](g), phenol, Cl[sub 2](g), H[sub 2]S(g), SO[sub 2](g) was performed in a continuous-flow processing system with the tris[5-amino-1.10-phenanthroline]Fe[II] polymeric film-coated glassy-carbon electrode as detector. It was concluded that the charge compensation through counter-ion motion did play a significant role in electron transport through the polymer film and the responses increased with increase in the ionic mobility for anions with similar structure. The collected observations gave valuable reference for the selection of supporting electrolytes in the determination of certain analytes. This type of electrode proved to be a very sensitive and long lasting sensor, especially for NO[sub 2](g) and phenol. Experimental parameters such as pH, flow rate, and sample size were optimized for the NO[sub 2](g) detection.
