Electrocoagulation Process for the Removal of Reactive Orange 16 Dye using an Aluminium Electrode

Abstract

Industrial wastewater, especially from the textile industry, contains synthetic dyes like Reactive Orange 16 (RO16), an azo dye with strong, persistent coloration that poses serious ecological and health risks. Conventional wastewater treatment methods, such as chemical coagulation, generate toxic sludge and residual chemicals, while biocoagulation lacks efficiency due to longer retention times. Electrocoagulation (EC) offers a promising alternative for RO16 removal, with the potential to reduce pollutant levels without additional chemical inputs. The objective of this study is to determine the effectiveness of electrocoagulation (EC) for RO16 dye removal by analyzing contaminant parameters dye concentration and NaCl dosage and operational parameters voltage and time treatment.
