| Abstract | |
Electrochemical reduction of the azo dye disperse orange 1 (DO1) was performed by square wave and cyclic voltammetry using a boron-doped diamond electrode. The dissolution of DO1 was evaluated by monitoring the UV-Vis spectra of the solutions, and best results were obtained using aqueous solutions containing 5 % Fongranal FB dispersant. Three irreversible peaks were obtained for the electrochemical reduction of DO1, while the dispersant showed one irreversible peak. The overall electrodic process was mainly diffusion controlled. A mechanism is proposed for the reduction of the dye. (AU) | |
