Description This study examines the decolourization of Reactive Black 5 (RB5) dye in aqueous solution and textile wastewater treatment
by sono-electro-chemical method to obtain synergistic efect. The electrolytic cell equipped with stainless steel anode and
graphite cathode was used for this study. Sodium persulphate (NaS) and manganese sulphate (MnS) are used as electrolytes
to facilitate the process. The efects of various operational parameters such as initial solution pH, NaS concentration, MnS
concentration, ultrasound power and voltage on the sono-electro-chemical treatment were investigated. The results have
demonstrated that the enhanced colour removal efciency was achieved at pH 2 for electro-chemical process; however, better
efciency was reached by synergistic efect of sono-electro-chemical treatment in the presence of less amount of electrolytes
with the short reaction time than the individual sono-chemical and electro-chemical process. The maximum decolourization
achieved was 89% under the condition: 100 ppm RB5, 50 ppm NaS, 75 ppm MnS, solution pH and 44 W ultrasound power,
20 V. When the similar methodology was adopted to real textile efuent, 90% of TOC removal was observed and it indicates
the employment of studied process for industrial wastewater treatment purposes.
