“…Comparing the test results with aluminum electrodes (R = 98.96 %), we can say that iron is also effective in removing DY. The reactions involved in the EC using iron electrodes are as follows: The iron, after oxidation in the electrolytic system, produces iron hydroxide Fe(OH) n (s), with n = 2 or 3; and two mechanisms have been proposed [6,12,14,15,24,38] …”
