Abstract Ammonia nitrogen (NH 4+-N) is one of the regular indexes and the most important
contaminants in drinking water. However, it is still a great challenge to remove low …

abstract Ammonia in the form of ammonium ion is toxic and could decrease the dissolved
oxygen in water and endanger the aquatic life. The aim of this study is the removal of …

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 process (COP) is considered as a cost-efficient technology for the
treatment of refractory chemical wastewaters. The catalyst performance plays an important …

Catalytic ozonation of ammonia nitrogen (NH 4+-N) in wastewater has received widespread
attention in recent years because of its high efficiency and mild reaction conditions …

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), which exists in the dominant form of ammonium ion
(NH 4+) under the pH of 6.5–8.5, is one of the regular indexes and the most important …

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

In this study, a novel NiAl2O4/NiO@ γ-Al2O3 catalyst was prepared by the impregnation-
calcination method and used for the catalytic ozonation of tartrazine wastewater. The …

Simultaneous removal of NO x and SO2 during the wet absorption process has made it
possible for nitrogen resource utilization. However, nitrites formation at high ratio in …
