ABSTRACT: Nano-Fe2O3/goldmine complex
was obtained by chemical coprecipitation reaction on the surface of goldmine
waste-solid. Being used as the heterogeneous catalyst in Fenton-like advanced
oxidation processes (AOPs), its treatment effect was studied in the removal
performance of industrial dyes effluent. Although the maximal COD removal
efficiency would reach 35.4% when 5 mL NaClO was added in 100 mL industrial
dyes effluent, it is found that by using nano-Fe2O3/goldmine system, the COD
removal efficiency of 13,000 mg/L dyes wastewater could reach up to 75.5% in
the presence of 30 g/L nano-Fe2O3/goldmine complex and 50 mL/L NaClO at 50。C.
