Graphite electrodes were used as the anode and cathode for the decolorisation process. The parameters such as applied current, initial pH, solution conductivity, interfering ions, and effect of electrodes were optimised. It was found that the dye with an initial concentration of 20 mg L-1 could be removed after 50 min using a current of 100 mA with colour removal of up to 94 %. The UV-VIS spectra of the dye were analysed prior to and after treatment and these confirmed that the conjugated systems were decomposed at a current of 100 mA. The optimised method was successfully applied to real wastewater samples.eninfo:eu-repo/semantics/closedAccessdyedecolorisationelectrolysisUV-VIS spectrophotometryArticle68111491149710.2478/s11696-014-0616-92-s2.0-84912137137Q2WOS:000341735100007Q3
