This article reviews the electrochemistry and electroanalytical applications of carbon paste-based electrodes, sensors, and detectors on the occasion of the half-of-century anniversary since the discovery of carbon paste. The review (with 333 references) has been prepared in the form of a retrospective compilation presenting the field by means of various facts, notes, data, surveys, and summaries, including numerous rarities or curiosities that illustrate the individual achievements and milestones. Carbon paste-based electrodes are discussed in their entirety by covering all important areas of the field, starting from basic characterization of carbon paste as the electrode material, via its typical physicochemical and electrochemical properties or specific features, up to a representative documentation of their applicability in electrochemical and electroanalytical measurements.

“…CPEs can also discriminate between extraction and adsorption, which may be useful for analyzing mixtures of substances with otherwise very similar electrochemical behavior [64, 651. Extraction can be used advantageously for selective accumulations of some metals via their anions [59, [66][67][68]. The adsorptivity of some compounds (in particular lipophilic molecules) on CPEs can be higher than on their solid counterparts, again due to the pasting liquid [33, 34, 44, 691. Other types of interaction between the pasting liquid and target analyte can also be exploited for accumulation, for example, ion pairing [66,671 or electrostatic binding [15, 701.…”

A review is presented dealing with the use of carbon paste as an electrode material for electrochemical sensors (3 11 references). It covers mainly publications which appeared during the period 1990-1993; numerous applications demonstrate the widespread applicability of carbon paste in the field of electrochemical analysis, such as voltammetry, amperometry, and potentiometry, but also as an electrode for electrochemical detectors in flow systems.

“…It was used for the determination of uranium. Other examples are the determination of mercury [13][14][15], bismuth [16], gold [17,18], silver [19] and europium and ytterbium [20]. Graphite paste electrodes with bulk modifiers act in a similar way as surface-modified electrodes.…”

In this review the combination of voltammetric methods of analysis with separation techniques, such as electrochemical separations, extractive separations, chromatography, electrochromatography, electrophoresis, volatilization and coprecipitation is critically discussed. Based on available publications and their own experience, the authors try to evaluate different separation techniques in view of future developments, paying special attention to extraction methods. For organic analysis, chromatography and electrophoresis with voltammetric detection are considered to be especially attractive while for stripping analysis, major progress is expected to be made in the development of electrodes and electronic equipment. Extraction, coprecipitation and volatilization will be of minor significance.
