Abstract
The present invention relates to an ozone water that has the potential to find useful applications in a wide variety of technical fields and is capable of maintaining the effects of wiping out microorganisms such as bacteria, viruses and the like and inhibiting the growth thereof over long periods. The present invention provides ozone nano-bubbles capable of staying in a solution for an extended period of time and a method for producing the ozone nano-bubbles by instantaneously shrinking the diameters of ozone microbubbles contained in an aqueous solution by the application of a physical irritation to the ozone microbubbles in an aqueous solution.
Claims9
An ozone water comprising an aqueous solution containing ozone nano-bubbles which hold ozone therein, the bubbles having a mean diameter of about 140 nm with a standard deviation of about 30 nm, with each of the ozone nano-bubbles surrounded by an inorganic shell consisting predominantly of electrolytic ions of iron, manganese, calcium, sodium, or magnesium, which inhibits the ozone nano-bubbles from dissipating.
A method for producing an ozone water, comprising the step of instantaneously shrinking ozone-containing microbubbles with diameter of 10 to 50 μm in an aqueous solution to generate ozone nano-bubbles having a mean diameter of about 140 nm with a standard deviation of about 30 nm by the application of a physical irritation to the ozone-containing microbubbles in the aqueous solution after the addition of electrolytic ions of iron, manganese, calcium, sodium, or magnesium, to the aqueous solution so that the electric conductivity of the aqueous solution reaches more than 300 μS/cm, wherein the ozone nano-bubbles with the mean diameter of about 140 nm, with a standard deviation of about 30 nm, are surrounded by an inorganic shell consisting predominantly of electrolytic ions of iron, manganese, calcium, sodium, or magnesium, which inhibits the ozone nano-bubbles from dissipating and are found to be stable in water after one week when the ozone water is placed in a glass bottle, and stored in a cool, dark place with the bottle being covered with a lid.
