Stripping potentiometry signal enhancement using mercury film-coated reticulated vitreous carbon working electrode Original Research Article

The effect of enhancement of stripping potentiometry signals of trace metals by using a mercury film coated reticulated vitreous carbon flow-through electrode is described. The advantage of such a system is the possibility of the efficient in situ removal of oxygen by exhaustive electrolysis in a small electrode volume during the short stop of the flow after the main deposition time. This results in a considerable enhancement of the analytical signals and also a time saving due to elimination of the unnecessary deaeration procedure.
