Degradation of Basic Red 46 dye from color wastewater using cold atmospheric plasma

Abstract

Contamination of groundwater with colored and toxic wastewater causes many environmental problems and adversely affects human health. In this study, Basic Red 46, the decolorization of textile dye, Basic Red 46, was studied using advanced oxidation processes (AOPs) in a non-thermal plasma reactor. The reactor uses a high voltage AC power source and airflow based on pin-to-water high-voltage corona discharge. The rate of the dye removal for 100 ml of this solution was investigated. The results showed that the corona discharge exhibited 85 % degradation efficiency for 50 mg/l of basic Red 46 within 30 min of treatment time.
