As one of the most important water pollutants, ammonia nitrogen emissions have increased
year by year, which has attracted people's attention. Catalytic ozonation technology, which …

Catalytic ozonation based on heterogeneous metal oxides is a promising approach to
removing ammonia as gaseous nitrogen from water. Herein, MgO/Co 3 O 4/CeO 2 was …

It is highly concerned to explore heterogeneous catalysts of metal oxides to remove NH 4+-
N in the wastewater, in which NH 4+-N can be greatly oxidized as gaseous nitrogen in the …

Ozone oxidation and ozonation catalyzed with MgO were applied to remove ammonia in
water at low temperature (10℃). Results show that pH played a critical role in both …

In this study, the reaction mechanisms for ozonation of ammonia nitrogen in the presence of
Co 3 O 4 or MgO were investigated. For the reaction over Co 3 O 4, Cl–in the reaction …

Catalytic ozonation was reported to be a highly selective method for transforming ammonia
nitrogen to N 2. However, the mechanisms of ammonia oxidation were confusing to be …

In this work, CTAB-NiO catalyst was prepared by solid-state method and employed for
oxidizing ammonia (NH 4+) in aqueous solution by catalytic ozonation. In order to obtain …

Abstract Ammonia nitrogen (NH 4+-N) is the most common pollutant in wastewater, which
consumes dissolved oxygen in water and causes eutrophication in water bodies, and is an …

Catalytic ozonation is a new method used for removal of NH4OH solution. Therefore, high
catalytic performance (activity and selectivity) should be achieved. In this work, we report the …

Large amounts of water containing-ammonium nitrogen (NH 4+-N) have attracted increasing
attention. Catalytic ozonation technology, involving the generation of hydroxyl radical (· OH) …
