عنوان انگلیسی An Investigation on the Treatment of Wastewater Disperse Dye by Electrocoagulation and Examine the Use of the Treated Dye for Flora and Fauna
چکیده انگلیسی مقاله The removal of disperse dye from wastewater is a critical and time-consuming task along with a significant issue raised by disperse dye in the development of toxic aromatic amines. Electrocoagulation (EC) is an advanced and economical water treatment technology that is successful in treating textile wastewater. However, the major issue in the EC process is on the choice of the electrode. In this study, the performance of Titanium (Ti)-Aluminium (Al) electrode on the degradation of aqueous Disperse Orange 30 dye at various operating conditions was studied. At pH 6, reaction time of 30 min and 10 V, the maximum removal efficiency of 97% was attained. The sludge was analyzed by EDX and the dissolution of Ti was less during the process. The formation of titanium oxide/hydroxides/oxynitride were confirmed by XPS analysis done on the sludge. To reuse the treated dye solution, it was subjected to ICP-OES analysis to determine the concentration of metals present. The results revealed that the solution contained 0.164 mg/L of Al and 0.001 mg/L of Ti indicating that the treated water can be reused. Phytotoxicity and eco-toxicity tests were performed on Brassica nigra and Catla catla, and it was found that the parameters tested with treated dye solution produced similar results to the control. The overall results reveal that Ti electrode dissolution was low and the dye water treated with Ti-Al electrode was appropriate for reuse.
