THE APPLICATION OF ELECTROCOAGULATION PROCESS FOR THE REMOVAL OF TARTRAZINE DYE FROM SIMULATED WASTE WATER SYSTEM

The dyeing and finishing operations in textile indu stries contributes a major share to wastewater gene ration. This is hazardous to our environment and ecosystem. Tartrazine, a yellow menace, is widely being used in cosmetics, foodstuffs, medicines and textile. It is carcinogenic and also catalyzes allergic problems. The present study emphasized on the removal of dyes from simulated waste water by Electrocoagulation method. It was proceeded by electrode/electrolyte interface. Iron and steel electrodes were selected for the process and NaCl was used as an electrolyte to treat the wastewater. Th e effects of operating parameters such as time, concentration, pH and electrolysis potential on the decolourization and removal efficiency were invest igated. Furthermore, the mechanism of electrocoagulation was also elucidated. The results indicated that electrocoagulation was a very effective process for the rapid decolourization of textile effluent and able to achieve maximum % removal capacity.
