“…Various modifications of carbon paste were applied in potentiometric sensors for copper [286][287][288][289][290][291][292], silver [97, 153,293], mercury [94-296], lead [297], arsenic [97,298], antimony [299], bismuth [300], cobalt [301], osmium [302], aluminium [107], lithium [303], ammonium [304], halides and pseudo-halides [305][306][307][308], and sulphate ions [309]. Some of them [97,302] were applied to monitor titrations based on ion-pair formation principles described and discussed in detail previously [310].…”

Abstract:In this review (with 500 refs), both electrochemistry and electroanalysis with carbon paste-based electrodes, sensors, and detectors are of interest, when attention is focused on the research activities in the years of new millennium. Concerned are all important aspects of the field, from fundamental investigations with carbon paste as the electrode material, via laboratory examination of the first electrode prototypes, basic and advanced studies of various electrode processes and other phenomena, up to practical applications to the determination of inorganic ions, complexes, and molecules. The latter is presented in a series of extensive tables, offering a nearly complete survey of methods published within the period of [2001][2002][2003][2004][2005][2006][2007][2008]. Finally, the latest trends and outstanding achievements are also outlined and future prospects given.© Versita Warsaw and Springer-Verlag Berlin Heidelberg.

“…drugs [26][27][28][29][30][31] polyesters with pendant amino groups and carbonyl oxygen of the ester group as donor sites per unit may yield metalcoordinated polymers with interesting properties. However, few investigations had been reported on the synthesis of polyesters having amino acid moieties in the main chain.…”

“…The advantages of carbon paste electrodes, such as chemical inertness, robustness, low cost, renewability, very low background current, stable response, low ohmic resistance and no need for internal solution over conventional polymeric membrane and coated wire electrodes has attracted the attention of researchers in recent years [24][25][26][27][28].…”

A comparative study was made between three types of Cr(III) ion-selective electrodes: PVC membrane electrode, silver coated electrode and modified carbon paste electrode based on N,N-bis(salicylidene)-o-phenylenediaminatechromium(III) complex (Crsalophen). As anticipated, electrodes with a solid contact, rather than a traditional liquid inner contact, give lower detection limits because of diminished ion fluxes. Often, however, ill-defined solid contact gives rise to instabilities and interferences by oxygen gas. The carbon paste electrode provides a more sensitive and stable device than that afforded by PVC and coated electrodes. The best performance was obtained by an electrode based on the paste containing 3.5 wt% Cr-complex, 48.5% graphite plasticized with a mixture of 24.0 wt% tris(2-ethylhexyl) phosphate (DOPh) + 24.0 wt% dioctyl sebacate (DOS). The sensor has a linear dynamic range of 7.5 × 10 -6 to 1.0 × 10 -2 M, with a Nernstian slope of 20.1 ± 0.6 mV decade -1 , and a detection limit of 1.8 × 10 -6 . It has a short response time of a bout 8 s and is applicable in a pH range of 4.5-7.7. It was successfully used as an indicator electrode in potentiometric titration of Cr(III) with EDTA and in determination of Cr(III) in water samples and chromium in (Crsalophen).
