ABSTRACT
In this paper, four degradation methods of carmine wastewater were studied. The results showed that electrochemical oxidation-persulfate-Fe2+ displayed the best performance. The decolorization rate and energy consumption reached 98.85% and 1.44kW·h/kg at 10.0 min when the current was 0.5 A with 2.0 mmol/L persulfate and 0.5 mmol/L FeSO4.
