Abstract:
|
In this work, an electrochemical treatment in a batch cell with Ti/Pt anode was applied to degrade two
reactive dyes (Color Index Reactive Orange 4 and 13) in the presence of chloride ions, usually used as
dyeing electrolyte. For the two dyes, the kinetic of degradation was studied and also kinetic constants
were modelled. The influence of several factors such as pH, conductivity, dye concentration and reactive
group structure were evaluated. The adjustment of the established models was also studied. |
