Treatment of Dye Wastewater by Nano-Ferrous Modified Bentonite Assisted Advanced Oxidation Processes

Abstract:

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.
