Waste Gas

The catalytic oxidation of NOx from waste gas was investigated using advanced oxidation process based on sulfate radicals. The manganese oxide immobilized on graphene oxide (GO) can activate peroxymonosulfate (PMS) for the oxidation of NOx in water. The Mn3O4/GO catalyst system exhibited efficient activity for NOx oxidation when the Mn3O4/GO catalyst loaded an optimum Mn3O4. In addition, 52.28% oxidation could be achieved within 60 min with 0.25 mM catalyst, and 2 mM PMS. Therefore, the results may have significant technical implication for utilizing Mn2+/PMS to oxidize NOx for offgas treatment.

Heterogeneous Catalytic

Heterogeneous catalytic ozonation (HCO) of wastewater is gaining both research and industrial interests. It is proved to be an advanced oxidation process since it involves hydroxyl radicals as oxidation species. Few studies have been carried out to test HCO in the treatment of landfill leachates. This work has been carried out to test three types of catalysts: activated carbon (AC), expanded perlite (EP) and titanium dioxide (TiO2) combined with ozone at 80 g/m3 gas concentration for the treatment of a leachate generated by Jebel Chakir landfill site near Tunis–capital of Tunisia. The work has shown a reduction in COD of about 45% and an increase in biodegradability (BOD5/COD) from 0.1 to 0.34. A catalyst concentration of 0.7 g/L was found optimal for the treatment of the leachate.

We have recently reported that the reaction of H2O2/IO4− could be a new advanced oxidation process for water treatment [N. E. Chadi, S. Merouani, O. Hamdaoui, M. Bouhelassa and M. Ashokkumar, Environ. Sci.: Water Res. Technol., 2019, 5, 1113–1123].
