“…curves is probably due to an anodic polymerisation at the electrode. Similar polymerisations have been found by AZbery et al [25] [26] with thionine. If the electrode is removed from this solution, washed, and placed in background electrolyte (1 M H2S04), the CV.…”

“…The attachment may be obtained by coating with a polymer [ 1-81, chemical binding [9-181, [12]. A survey of chemically modified electrodes has been given in some review articles [27-291. Attaching organic redox systems to electrodes can be realized by adsorption or polymerisation [25] [26]. During some photogalvanic experiments with phenazine [30], we recognised an adsorption at the electrodes, which altered the electrode behaviour markedly.…”

SummaryGlassy carbon and gold electrodes were coated with 1-hydroxyphenazine, and the electrochemical properties of these electrodes were tested using them as a rotating disc electrode to reduce Ru ( b i~y )~~+ , (Ell2 = -460 mV vs. SCE. on a Hg-electrode in 1 M HC1) takes place at -100 mV.The heterogeneous rate constant depends on the second order reaction between the attached coating and the redox couple in solution. Depending on this rate constant, selectivity of the electrode is observed.Introduction. -Recently, there has been an increasing interest in electrochemistry of so-called chemically modified electrodes. These electrodes are prepared by attaching irreversibly an electroactive substance to a conducting material (eg. on Pt, graphite, glassy carbon). The attachment may be obtained by coating with a polymer [ 1-81, chemical binding [9-181, or This report describes some electrochemical properties of these electrodes.

“…However, among azines, only thionine ( Figure 5.1) was successfully electropolymerized from acidic solutions [4][5][6]. On the other hand, in the case of methylene blue ( Figure 5.1) in such conditions, only a minor amount of electroactive polymer was obtained [7,8].…”

Logarithmic analysis of polarographic waves complicated by nonparallel initial and limiting currents

1992

View full text Add to dashboard Cite

A procedure for the logarithmic analysis of polarographic waves w t h nonparallel initial and limiting currents is developed and its application illustrated with 1 x 7 0 experimental systems: phosphinemetriphonate reduction and methylene blue (MR) reduction and reoxidation. The procedure is based on the presumed identity of the wave function and the change of a double-layer capacitance along the wave. WORDS: Polarography, Data handling, Double layer capacitance. From a d.c. polarogram of a certain redox reaction, several important electrochemical parameters can be determined [ 1-31. A reactant concentration and a prod-
