V originále

Cyclic voltammetric (CV) study of electrooxidation of monochlorophenols (2-chlorophenol, 3-chlorophenol, 4-chlorophenol) on a Pt electrode in 0.5 M H(2)SO(4) was combined with the experiment using electrochemical quartz crystal microbalance (EQCM). For all chlorophenols the polymeric film formation on the electrode surface has been observed and the electrode surface was completely covered with polymeric film after five cycles. Partial deactivation of the electrode resulting in the formation of the more permeable film was created in the case of 2-chlorophenol and the film of 4-chlorophenol was created also with the low permeability. The influence of the scan rate on the electrooxidation of chlorophenol was evaluated. It was found that the lower electropolymerization rate and better permeability of the film was observed at higher scan rates. Valuable insights into complex electrooxidation processes of all chlorophenols were also gained by means of the elimination voltammetry with linear scan (EVLS). The EVLS functions, eliminating two current components, reveal a strong adsorption state of 3-chlorophenol and show differences in electrochemical behavior of chlorophenols in all cycles. From the comparison of elimination results of corresponding derivatives the different mechanism of electrooxidation was suggested.
