Advanced peroxynitrite oxidation technology is one of the methods for deep treatment of trace and persistent organic pollutants in water, with simple operation and rapid process. This technology uses persulfate as oxidant and achieves oxidative degradation of pollutants by generating reactive oxygen species such as SO4--, -OH, O2-- and 1O2. Among them, the non-radical 1O2 has a mild oxidation capacity, a long half-life, and exhibits reaction selectivity for electron-rich organic pollutants as well as a stronger resistance to inorganic ions and organic background interference. Therefore, the 1O2-dominated non-radical degradation pathway offers new possibilities for the selective removal of organic pollutants from water. Meanwhile, the precise regulation of 1O2-dominated non-radical oxidative degradation is gradually becoming a research hotspot.
