“…It has been found that the thermal stirring effect at the 25 m gold wire used was more efficient than the convection at a rotating disk electrode. Heated mercury film electrodes [112,113] have been used to determine metallic traces. A heated bismuth film electrode, tested for metallic trace determination [114] allowed the conclusion that this sensor could be a very good substitute for the traditional dropping mercury electrode.…”

Stripping analysis is a two-step procedure. In the first step, the analyte is accumulated at an electrode surface either by electrolysis or by adsorption. In the second step, the deposited material is removed, typically by electrolysis. The second step is the source of the analytical signal. Sensitivity of the method mainly depends on the amount of substance which is transferred to the electrode surface during accumulation. The methods reviewed make use of unconventional techniques to enhance efficiency of accumulation. By ultrasound, a combined action of thermal and mechanical impacts, partially with extreme energetic states, causes improvement of analytical results. Heating of electrodes or of a nearelectrode area induces laminar electrolyte flow acting as stirring, combined with increased surface temperature that is helpful to lower kinetic hindrances. Magnetic fields in a cell with arbitrarily increased deposition current enhances convection without additional thermal effects. Most of the techniques reviewed are able to improve the efficiency of stripping analysis much more than could be done by driving classical stirring up to the limits.

The second part of the review, which covers modified carbon-containing electrodes, describes composite and microelectrodes. Electrodes made of commercial and laboratory carbon-containing composite materials are discussed. Impregnated and thick-film electrodes and microelectrodes made of carbon fibers form a separate group. Various modifiers and methods of electrode modification are presented. Prospects for the future development of solid-state modified electrodes are considered. [12][13][14][15][16]. In most cases, electrodes of these materials are modified by metal films (mercury, copper, and bismuth), molecularly imprinted TiO 2 [17]. The occurrence in the last decade of new types of carbon materials "from carbon nanotubes to edge plane pyrolytic graphite" [18,19] has significantly changed the scope and sensitivity of electroanalytical methods for the measurement of diverse targets from metals ions to biological markers. Investigators considered in detail electrochemical characteristics [20] and practical use [21] of the "edge" plane pyrolytic graphite, which proved to have a wider interval of working potentials and a low detection limit as compared to those of the basal pyrolytic graphite and GC. For example, in situ bismuth film modified edge plane pyrolytic graphite electrode was successfully applied to the ultra trace simultaneous determination of cadmium(II) and lead(II) with detection limit 5.5·10 −10 and 4·10 −10 M, respectively [22].Synthetic diamonds (nitrogen-[23, 24] and boron-doped ) have come into use quite recently for electrochemical measurements. In particular, a gold-coated, borondoped, diamond thin-film electrode was used for total inorganic arsenic detection in real water samples [50]. Unlike properties of other carbon materials, which are widely used in electroanalysis, properties of synthetic diamonds became the subject of comprehensive study just about 10 years ago. The research was hindered by two circumstances: shortage of the material and the absence of conduction. The situation radically changed with the advent of highly efficient methods for growing of polycrystalline diamond compounds.A more efficient separation, accumulation, and determination of components is achieved with electrodes of composite materials made of graphite, carbon, glassy carbon, or diamond powders and binders such as paraffin, epoxy resins, methacrylate, silicon, styrene-acrylonitrile copolymer, polyester, and silica gel. The reviews [51][52][53][54] deal with properties and applications of various composite J Solid State Electrochem

“…A renewed interest for temperature effects on the interfacial electrochemical processes has been observed in the last decade [1][2][3][4][5][6][7][8][9]. Indeed, greater attention has been devoted to the effects of the heated electrode and its temperature modification, either for stationary or dynamic regimes [5][6][7][8][9][10][11][12][13][14][15][16] by modulating the electrode temperature [10][11][12][13] or using temperature jump techniques [14,15].…”
