Chlorine dioxide (ClO)2) Is a gas from yellow green to orange yellow, is a safe and nontoxic green disinfectant recognized internationally, can effectively oxidize enzymes containing sulfydryl in cells, and has better killing effect on bacteria, spores, viruses, algae, fungi and the like. Chlorine dioxide (ClO)2) Has no 'three-cause' effect (carcinogenesis, teratogenesis and mutagenesis), and simultaneously does not generate chlorination reaction with organic matters in the disinfection process to generate organic chloride or other toxic substances which can generate 'three-cause' effect, thereby being safe and having no residue. Chlorine dioxide (ClO)2) The disinfectant has the characteristics of strong sterilization capability, no harm to human bodies and animals, no secondary pollution to the environment and the like, so that the disinfectant is popular with people. Chlorine dioxide (ClO)2) Not only is a broad-spectrum environment-friendly sterilization disinfectant without generating carcinogens, but also has remarkable effects in sterilization, food preservation, deodorization and the like. Chlorine dioxide (ClO)2) It can also be used for bleaching, such as chlorine dioxide for textile and papermaking elements.
Chlorine dioxide (ClO)2) When meeting hot water, the raw materials are decomposed into hypochlorous acid, chlorine and oxygen, the raw materials are easy to decompose under the action of light, the preparation process is relatively complex, and the raw materials are produced and used by a binary activation method in general markets, so that the dosage and the effect are difficult to master.

The chlorine-containing disinfectant as set forth in claim 3, wherein the nano-borate-containing complex is a nano-complex of borate with a size of 5-200nm formed by polyvinyl pyrrolidone as a carrier and potassium iodate, polyaluminum chloride, water-soluble phosphate, water-soluble silicate or water-soluble carbonate, the borate is metaborate, orthoborate, polyborate or perborate, and the cation of the borate is calcium ion, magnesium ion, sodium ion, iron ion or manganese ion.
6. The disinfectant containing chlorine as claimed in claim 5, wherein the borate is prepared by reacting polyvinyl pyrrolidone as a carrier with potassium iodate, polyaluminum chloride, water-soluble phosphate, water-soluble silicate or water-soluble carbonate at 100-120 deg.C for 1.0-2.0 hr while adjusting pH to 10-12 to form nano-crystallites, i.e. nano-complex.
7. The chlorine-containing disinfectant according to claim 3, wherein the anionic surfactant is present in an amount of 0.01 to 1% by weight based on the total weight of the chlorine-containing disinfectant, and the nanoboric acid-containing complex stabilizer is present in an amount of 0.2 to 3% by weight based on the total weight of the chlorine-containing disinfectant.
8. The process for preparing a chlorine-containing disinfectant as claimed in claim 1, wherein the excess sodium chlorate or sodium chlorite is stably decomposed into chlorine dioxide under acidic conditions, and the chlorine dioxide and the peroxide molecule complex is obtained by reacting the chlorine dioxide and the alkali solution of sodium peroxide or hydrogen peroxide in water, wherein the molar ratio of the chlorine dioxide to the sodium peroxide or the hydrogen peroxide in the complex is 3-5: 1, and further, an anionic surfactant and a complexing stabilizer containing nano boric acid are added to make the contents of the anionic surfactant and the complexing stabilizer respectively reach 0.01-1% and 0.2-3% of the total weight of the chlorine-containing disinfectant.
9. Use of a chlorine-containing disinfectant as claimed in any of claims 1 to 7 for killing pathogenic bacteria.
10. Use of a chlorine-containing disinfectant as claimed in any one of claims 1 to 7 for killing a novel coronavirus covi-19.
