Abstract

Provided is a method for producing a high-concentration long-acting ozone nanobubble aqueous solution capable of maintaining ozone concentration for a long period of time at room temperature. A microbubble generator is adopted to produce ozone nanobubbles in an aqueous solution in which a bubble-retaining agent is dissolved, so that ozone nanobubbles having a particle size of less than 500 nm areproduced in excess of 129*108 / 100 mL, and the bubbles can stably remain in the aqueous solution for a long period of time. The ozone concentration of the ozone nano-bubble aqueous solution is 18.5-63mg / L; and the ozone concentration of the ozone nano-bubble aqueous solution can still be kept above 60% after the ozone nano-bubble aqueous solution is sealed, shaded and stored for three months at normal temperature. The ozone nano-bubble aqueous solution has higher sterilization capability than existing ozone water. The aqueous solution can be applied to the fields of medical treatment, sanitation, industry, food processing, agriculture, breeding industry, fresh keeping, disinfection, decontamination, deodorization, washing, family individuals, pets and the like.

Description

technical field [0001] The invention relates to a high-concentration long-lasting ozone nano-bubble aqueous solution and a preparation method thereof, belonging to the technical field of preservative ozone nano-bubble preparation. Background technique [0002] Water dissolved with ozone gas is called ozone water. As we all know, ozone water and ozone gas have the same strong oxidizing ability. Ozone water is widely used in sterilization, disinfection, preservation, deodorization, cleaning, decolorization and other fields. Ozone will oxidize respiratory tissues and cause damage to living tissues, but ozone water is harmless to living tissues (except for ozone gas dissipated in the air) and has no residue. The U.S. Food and Drug Administration (USA Food and Drug Administration) listed ozone water as a food additive in 2001, which can be used for sterilization in food factories and food sterilization. The decomposition rate of ozone in water is faster than that in air. The hal...
