“…Forsberg et al [27] investigated in detail the determination of arsenic by ASV and differential pulse anodic stripping voltammetry (DPASV) at various electrode materials (HMDE, Pt and Au), of which gold was found to be most suitable because of its sensitivity and high hydrogen overvoltage. In addition to solid gold electrode, macro-sized gold film electrodes [28,29] have also been used and the re-plating and washing [30] and reactivation of electrode surface [31] before each measurement improved the reproducibility. Besides, Bodewig et al [32] and Sun et al [33] investigated arsenic determination on gold rotating disc electrodes to remove produced hydrogen bubbles mechanically.…”

This review describes recent results regarding voltammetric and amperometric determination of submicromolar concentrations of various environmentally important biologically active organic substances using nontraditional types of electrodes either in batch analysis or in flow liquid systems (especially HPLC or FIA with electrochemical detection). Attention is paid to solid amalgam electrodes (environmentally friendly alternatives to mercury electrodes), to carbon paste electrodes with easily renewable surface, to boron doped diamond film electrodes with very low noise and broad potential window, and to inexpensive solid composite electrodes with high signal-to-noise ratio, compatibility with organic solvents and easy mechanical or electrochemical pretreatment. The review concentrates on our own results in the context of the general development in the filed.

“…Specific features of the last material are its strength, chemical inertness, absence of impurities, nonswelling in water solutions, stability in organic solvents for prolonged periods, ease and simplicity of fabrication, and secure fixing of water-soluble reagents. Table 1 gives examples of the use of modified composite electrodes in stripping voltammetry with the composite materials made under industrial and laboratory conditions using simple sol-gel, sono-gel, spin-casting, and molding technologies [73,[74][75][76][77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92]. The electrodes shown in the table can be divided into two groups: those made of carbon-(soot, amorphous carbon) [73][74][75][76][77][78][79] and those made of graphite-containing [80][81][82][83][84][85][86][87][88][89][90][91][92] materials.…”

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
