Evaluation of Hydrophilized Graphite Felt for Electrochemical Heavy Metals Detection (Pb2+, Hg2+)
Figure 4
Square wave voltammograms using graphite felt electrode in 0.1 M sodium acetate/acetic acid buffer at pH 4.5 containing M of Cd2+. Note that a shift of the baseline related to the capacitive current of the graphite felt.
