The present invention: add the carbonylated carbon material to the sewage to be treated and stir, then add the aqueous solution of persulfate to obtain a mixed solution, and continue to stir the mixed solution to generate singlet oxygen to treat the sewage; the patent of the present invention is high-efficiency , The directional generation of singlet oxygen provides a new method, and at the same time, the method is safe, economical and environmentally friendly, and can be applied in the fields of biomedicine and water treatment, and its market prospect is broad. The invention is applied in the field of water treatment.

Description

technical field [0001] The invention relates to a method for directional generation of singlet oxygen. Background technique [0002] Singlet oxygen is an important active oxygen molecule. Its molecular orbital has a different electronic arrangement from that of ground-state oxygen molecules, and it is an excited state molecule of oxygen. Due to its high activity, it plays an important role in the fields of physics, chemistry, environment and biomedicine, and has attracted extensive attention from researchers. [0003] At present, the most common method for generating singlet oxygen is photosensitization, that is, the photosensitizer transitions to an excited state under light conditions, and then transfers energy to ground-state oxygen molecules to form singlet oxygen. However, there are still the following problems in this method: 1. The photosensitizers usually used are toxic and harmful substances (such as highly toxic porphyrin photosensitizers), so the application of t...
