Fig. 1. Schemes of the gliding arc discharge GAD: (a) GAD I, (b) GAD II, (c) GAD-FF, and (d) plate-channels.
Table 2 shows the standard potential values of some redox cou- cou-ples present in the GAD of humid air [39].
Fig. 3. Discolouration and degradation versus treatment time (number of cycles) and width of channels: ω = 1 L h −1 , ˛ = 45 ◦ , d = 5.5 cm, V = 180 mL, Q air = 700 L h −1 , i = 1 mm.
Fig. 5 shows UV/visible spectra of the AG25 treated in the new prototype as a function of plasma exposition time
