Nano-Fe2O3/goldmine complex was obtained by chemical coprecipitation on the surface of goldmine waste-solid. And its application as the heterogeneous catalyst in Fenton-like advanced oxidation processes (AOPs) was discussed for the degradation of dyeing wastewater. It was found that advanced oxidation processes play an important role to the removal of dyeing wastewater. And the best removal rate of 15400mg/L dyeing wastewater reached up to 63.1% with the presence of 50g/L dosage of nano-Fe2O3/goldmine complex and 50mL/L concentration of H2O2at 50°C with pH=3.

Oxidation Processes

Degradation of dye wastewater was studied by using nanoferrous modified bentonite as the heterogeneous catalyst for a Fenton-like oxidation. By comparing the effect of homogeneous Fenton reactions as well as heterogeneous Fenton-like process for nanomodified bentonite, it is found that the advanced oxidation processes assisted by nanoferrous/bentonite complexes exhibit the stronger degradation capacity. And the removal rate of Fenton-like reaction increased from 23.6% to 75.5% when the ferrous concentration increasing from 20 to 100mmol/L. Being compared with homogeneous Fenton reactions, 20% increased degradation efficiencies is obtained by Fenton-like oxidation process for nanomodified bentonite under 6g nanoferrous/bentonite complexes in 100mL dye wastewater.
