Comparison study of electrooxidation and photo-electroxidation for the
treatment of solutions containing Acid Blue 9 dye
The objective of this study is to investigate the contribution of light
energy in the electrochemical oxidation treatment of a solution
containing a model molecule, Acid Blue 9 dye (AB 9) using a low-cost
electrode elaborated by electrodeposition from a lead salt. The
elaboration procedure and the characteristics of the obtained Ti/b−PbO
2 electrode are given in the supplementary information.
First, electrolysis and I-E curves were performed in order to determine
the best conditions for dye removal and mineralization. Then the effect
of illumination is studied.
