Removal of Direct Red Dye 23 from Water and Wastewater Using S2O8 Oxidant Activated by UV Irradiation:An Investigation on the Operational Parameters
The photo-oxidative decolorization of Direct Red 23 (DR23), a textile dye which is suspected to be carcinogenic was investigated using peroxydisulfate activated by UV irradiation and heat in a batch photo-reactor at experimental conditions. A very simple analytical method, direct UV–vis spectrophotometric detection, was utilized for the progress of photo-oxidative decolorization of dye in aqueo...
