Colouring effluent from industrial activities may affect environment and human health. Many methods have been used to decolourise such effluent. However, the applicability of electricity to treat colouring effluent was not well defined. This study was performed to investigate the behaviour of decolourisation of solution containing Azo Acid Orange 7 under the influence of electricity. This study was focusing on the effect of decolourisation due to current density, dye concentration and duration of current flow. Simple electrochemical cell was prepared by using iron and steel plate electrode. The effectiveness of this method to decolorized dye solution was determined by measuring percentage of absorbance removal. From this study it was shown that the electricity are able to decolorize Azo dye more than 88% when the duration was 18 minutes and current density was 120 A/m2. Thus proved that decolourisation was affected by the amount of current density, duration of electric current flow and concentration of the dye.
