Analytical Applications Of Absorption Spectroelectrochemistry At Grazing Incidence, Julian Tyson

Chemistry Department Faculty Publication Series

Analytical applications of spectroelectrochemistry are limited by the short path-length, in the absorbing medium, that can be produced with most light-beam/electrode configurations. This disadvan­tage is overcome for grazing incidence. A cell fitted with glassy-carbon electrodes and used in a conventional spectrophotometer is described and applied to model systems illustrating the use of (a) homogeneous redox reactions, (b) homogeneous redox reaction followed by chemical reaction and (c) electro-deposition followed by stripping into a reagent solution. This last technique is the spectro­electrochemical analogue of anodic-stripping voltammetry.
