specific Embodiment approach 1

[0026] Embodiment 1: This embodiment is a method for activating persulfate directional generation of singlet oxygen by carbonylation carbon material, which is specifically carried out according to the following steps:

[0027] The carbonylation carbon material is added to the sewage to be treated and stirred for 5-10 minutes, and then an aqueous solution of persulfate is added to obtain a mixed solution, and the mixed solution can be continuously stirred to generate singlet oxygen to treat the sewage;

[0028] The carbon material in the carbonylation carbon material is amorphous carbon material, sp 2 Hybrid carbon materials and sp 3 A carbon material composed of one or two hybridization methods in the hybrid carbon material;

[0029] The concentration of carbonylation carbon material in the mixed solution is 0.01g / L~5g / L;

[0030] The concentration of persulfate in the mixed solution is 0.1 mmol / L to 10 mmol / L.

specific Embodiment approach 2

[0031] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the amorphous carbon material is activated carbon or mesoporous carbon. Others are the same as the first embodiment.

specific Embodiment approach 3

[0032] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the sp 2 Hybrid carbon materials are carbon nanotubes, graphene or fullerenes. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for directional production of singlet oxygen by activating persulfate via a carbonylation carbon material, and relates to the method for directional production of singlet oxygen. For solving the technical problems that a photosensitizer used in a method for producing singlet oxygen is a toxic and harmful substance, is not conducive to subsequent separation and is accompanied by generation of other active oxygen species. The method comprises the steps: adding the carbonylation carbon material into to-be-treated sewage, stirring, then adding an aqueous solution of persulfate to obtain a mixed liquid, continuously stirring the mixed liquid, and thus producing the singlet oxygen for treating sewage. The new method is provided for high-efficiency and directionalproduction of the singlet oxygen, and meanwhile, the method is safe, economical and environmentally friendly, can be applied in the fields of biomedicine and water treatment, and has wide market prospects. The method is applied to the field of water treatment.

Description

technical field [0001] The present invention relates to a method for the directed production of singlet oxygen. Background technique [0002] Singlet oxygen is an important active oxygen molecule, and its molecular orbital has a different electron arrangement from that of ground state oxygen molecule, and it is the existence form of 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 received 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, which then transfers energy to ground state oxygen molecules to form singlet oxygen. However, this method still has the following problems at present: 1. The commonly used photosensitizers are toxic and harmful substances (such as highly toxic porphyrin-based ...
