Cyclic Voltammetric Stripping (CVS) is one of effective electrochemical measuring techniques to obtain ideal stripping situation by utilizing Rotating Disk Electrode (RDE). This technique scans the potential at the working electrode which is immersed in the plating solution together with reference and counter electrodes through an electrochemical analyzer.
In CVS technique, working electrode can be both of anode and cathode depends on the scan direction. When the working electrode is anode, the current becomes posivite, cathode working electrode makes the current negative.
Oxidation reaction, removal of electrons from molecules or iones, occurs at anode in the electrocheical cell. On the other hand, reduction reaction, addition of electrons to molecules or iones, occurs at cathode. The potential is plotted on the X-axis and the current is shown on the Y-axis.
In CVS for copper plating, deposition occurs in reduction region. Reversal of the potential from reaction potential to oxidation potential triggers desorption of the copper.
