Design of a new UV/Vis-spectroelectrochemical measuring system
01.01.2008 - 31.12.2008
Electrochemical measuring techniques are used in different areas of chemical research and industry. These methods do not deliver structural information of generated products. Therefore electrochemistry is combined with spectroscopical techniques to obtain structural information.
The measuring system consists of a rotating (ring) disc elektrode, a fibre-optic light guide and a motorised positioning unit for the optical part.
The functionality of the system was verified electrochemically and spectroscopically. Potassium ferrocyanide (K4 [Fe(CN)6 ]) was used as test solution. The pale yellow potassium ferrocyanide (K4 [Fe(CN)6 ]) is oxidized to form orange ferricyanide in front of the electrode.
Further experiments will be carried out to demonstrate the suitability for studies of electrode kinetics.
