Chemically modified electrodes

1988
The electrochemical reduction of silver ions and the understanding of limiting currents by Solomen (1) was perhaps the first indication that voltammetry could be analytically useful. However, it was not until the introduction of a practical, reproducible working electrode, the dropping mercury electrode (DME), that the analytical utility of the ...

Chemically modified electrodes

2005
The historical development of chemically electrodes is briefly outlined. Following recent trends, the manufacturing of modified electrodes is reviewed with emphasis on the more recent methods of electrochemical polymerization and on new ion exchanging materials. Surface derivatized electrodes are not treated in detail.

Calixarene-Poly(dithiophene)-Based Chemically Modified Electrodes

Chemistry - A European Journal, 2001
The stepwise synthesis of cone and partial cone 1,3-bridged n-propoxy-calix[4]crown ethers ("monomers" 2 and 3) with an electropolymerizable 2,2'-dithiophene-3-yl-hexylene functionality at the lower rim, is described. The potential of 2 and 3 as sensing agents for alkali metal ions was investigated by 1H NMR titration experiments with NaSCN and KSCN ...

Chemically modified electrodes in liquid chromatography detection: A review

Talanta, 1991
Recent trends in the use of chemically modified electrodes (CMEs) in electrochemical detection systems used in flow-injection analysis or high-performance liquid chromatography are reviewed, with the objective of indicating the most promising approaches for practical CME applications.

The potentiometric response of chemically modified electrodes

Analytica Chimica Acta, 1996
Abstract The electrochemical polymerization of ortho-methoxyaniline and ortho-methylaniline was studied on platinum electrodes. The electrochemical response of electropolymerized films exhibits three well-defined redox processes similar to those observed for polyaniline.

Chemically-modified electrodes in photoelectrochemical cells

Canadian Journal of Chemistry, 1983
Tin oxide and titanium dioxide semiconductor electrodes have been covalently modified by the attachment of functionalized olefins and arenes through surface silanation or via a cyanuric chloride linkage. The excited state and electrochemical properties of the molecules so attached are significantly affected by the semiconductor.

Chemically modified carbon fibre electrodes

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1981
Abstract Anodic oxidation of highly oriented carbon fibres in 97% H2SO4 and subsequent reduction results in a high concentration of defects in the carbon crystal lattice. These defects are situated not only on the surface but also in the bulk of the fibres and may be oxidized to bulk functional groups.
