Abstract

The effectiveness of charcoal base metallic composite electrodes using commercial activated charcoal was investigated to fabricate an effective and low cost electrode to decolorize textile industries wastewater. The mixture of charcoal-graphite-metal powder (first layer) and graphite powder-polyvinyl chloride (second layer) was mixed together and later pressed at 10 toncm<sup>-2</sup> to form two layers pellet. C.I. Reactive Orange 16 (RO16) was chosen as the model dye because of its high resistance towards conventional treatment methods while NaCl was selected as supporting electrolyte. The electrode efficiencies were determined by percentage of RO16 decolorization. The effect of metal used, PVC percentage, composition of charcoal and graphite and duration of electrolysis time were examined and the results indicated that application of charcoal base metallic composite electrode using pellet with the composition of C<inf>30</inf>C<sup>G18</sup>Sn <inf>12</inf>PVC<inf>40</inf>-C<sup>G 60</sup>PVC <inf>40</inf> able to decolorized RO16 dye up to 83.3% respectively after 2 hours electrolysis time and increase proportionally with increase duration of electrolysis time. The study of activated charcoal base metallic composite electrode illustrated that reduction of PVC percentage also led to enhance in RO16 decolorization percentage. The decolorization of RO16 was determined by the changes of absorption spectrum intensity of azo chromophore (-N=N-) using UV-Vis spectrophotometer at λ = 388 and 492.50 nm.
