Plasma Treated Active Carbon for Capacitive Deionization of Saline Water

Figure 6

Comparison of cyclic voltammograms in 0.5 M NaCl for the untreated active carbon electrodes and the treated electrodes at different plasma power of 50 W, 75 W, and 100 W. From the CV curves, the capacitance at 0.25 V was calculated to be 120.32 F/g, 76.03 F/g, 599.89 F/g, and 151.70 F/g for the electrodes of untreated and treated at 50 W, 75 W, and 100 W, respectively.
