Irreversible cyclic voltammetry

WebThe cyclic voltammograms of SD at a bare GCE and MWCNT–GCE in 0.04molL 1 buffer solution (pH¼7) were shown in Figure 1. In the absence of SD, no redox peaks were observed at either the bare or modified GCEs during the cyclic voltammetry measurements within the potential window (Figure 1a and b). Compared to the bare GCE (Figure 1a), a large http://sop4cv.com/chapters/ElectrochemicalReversibility.html
