The application of chemically modified electrodes in analytical chemistry

Abstract

The applications of chemically modified electrodes to analytical chemistry have been reviewed. Five aspects, including electrocatalysis, selective preconcentration, permselectivity, specific recognization, and potentiometric responses are covered with 77 references.

Determination of Nanomolar Concentrations of Pb(II) Using Carbon Paste Electrode Modified with Zirconium Phosphated Amorphous Silica

“…CMEs are characterized by purposefully altering their surface characteristics to display new qualities that can be exploited for analytical purposes. The huge success of CMEs arises most often from the remarkable and sometimes unique properties of the modifiers [1]. They may exploit an accumulation step preceding the voltammetric determination.…”

Formation, Characterization, and Applications of Organic and Inorganic Nanometric Films

“…As a result, a new field of research termed chemically modified electrodes has evolved since the 1970s. [1][2][3] The thinnest films used for sufrace modification are monomolecular layers, i. e., self-assembled monolayers (SAMs), whereas the thickest films are usually made of polymers. This short overview will provide a few examples covering most of the thin-layer spectrum whereby electron transfer is controlled by a well-designed coating.…”

Modified carbon-containing electrodes in stripping voltammetry of metals

“…Therefore, the modification and the "molecular design" of the transducer surface and the formation of grafted layers on solid surfaces constitute an actively developing new area of investigation. Problems of the chemical modification of solid surfaces, specific and regular features of the modifier attachment to various solid matrices, and examples of practical applications of chemical sensors (modified electrodes) are overviewed in the papers [9][10][11][12][13][14][15][16][17][18][19][20][21].…”
