| Abstract: | The experimental study was performed with azo dye reactive bright red X 3B aqueous solution.The variables which influence decoloration of dyestuff and specific consumption of the bipolar packed bed cell were investigated.Effects of packing layers,applied cell voltage,flow rate,initial dye concentration,initial pH and species and concentrations of mineral salts were examined by parametric studies.The UV visible(VIS) absorption spectra of water samples before and after treatment indicated that conjugate chromogens in the molecular structures of azo dyes were destroyed,resulting in decoloration of dyes. |
