The degradation rate of the aza dyes brilliant black (blue ▪), diamine green (green ▾), and sudan I (orange •) during the electrochemical re‐oxidation of para‐periodate, j=312 mA cm−2, the flow rate was 7.5 L h−1, in a divided flow electrolyzer. All UV/Vis spectra were recorded in caustic soda (0.21 m Na3H2IO6, 4 m NaOH, 0.1 mm dye).
