Figures 2.11a and 2.11b show cyclic
voltammograms for the oxidation of furan in
methanol solution recorded at GC and Pt
anodes, respectively. An oxidation peak for
furan can be observed at a very positive
potential of 1.9 V vs. SCE using the GC plate as
the anode. In contrast, when the Pt plate is used
as the anode material, methanol solvent is
discharged more easily, a high background
current is recorded and therefore no oxidation
peak for the oxidation of furan is observed. It
can therefore be stated from the CV
experiments that GC is the better anode
material for the oxidation of furan.

oxidation of furan in methanol solution
recorded at (a) a GC plate anode and (b) a Pt
plate anode. Dashed curves indicate the
response in the absence of furan
As we have seen in the above example,
voltammograms measured in this process
