BEST MODE FOR CARRYING OUT THE INVENTION Embodiments will be described below. The silver ion water production method of this example is based on the previously known p
Manufacturing method by silver electrolysis in H8 or higher alkaline water, pH 5

Can be obtained efficiently .

It is generally known that various kinds of metals or non-metals exist in the underground resources existing in nature and each mineral contains a useful component which is different. Moreover, these minerals contain various minerals as well as many useful elements. In this example, among these minerals, Seitoku stone is used as a submarine volcanic rock containing abundant metal ions effective for electrolytically conducting silver in pure water. In this example, the following two methods were used to obtain the exudate from Shotoku stone.

As a first example, a well was excavated by boring in the bedrock of Shotoku stone, which is a kind of rock existing in nature, and a certain amount of groundwater was pumped from this well. The well water thus pumped is repeatedly concentrated in a predetermined temperature environment close to nature without any heating operation, and the concentration of metal ions dissolved in the well water is gradually increased. It was This results in acidity (eg pH 2.
A concentrated solution (stock solution) exhibiting 5 to 3) was obtained. It was confirmed that 1 kg of the stock solution leachate, Shotoku stone, thus obtained, contained the following kinds of complex metal ions as the components.

[0017] Hydrogen ion: 0.30 to 0.50mg Sodium ion: 0.30 to 0.60mg Potassium ion: 0.05 to 0.50mg Magnesium ion: 0.05 to 0.50mg Calcium ion: 0.50 to 1.10mg Manganese ion: 0.02 to 0.07mg Zinc ion: 0.02-0.07mg Lead ion: 0.002-0.005mg Copper ion: 0.01-0.02mg Aluminum ion: 7.00-14.00mg Iron ion: 40.00-65.00mg Chloride ion: 0.7-1.10mg Hydrosulfate ion: 18.00 to 25.00 mg Sulfate ion: 175.00 to 225.0 mg Metasilicic acid: 4.00 to 8.00mg Metaarsenic acid: 0.20 to 0.50mg Sulfuric acid: 0.10-0.30 mg

As a second example, Shotoku stone, which is a normally black brown mud-like hot spring sedimentary stone of submarine volcanic stone, which is dried in direct sunlight for about one month to give a grayish brown color Then, it was soaked in pure water for about 3 months, and the leachate (containing a plurality of types of metal ions ejected) was used as a stock solution. It was confirmed that 1 kg of the stock solution, which is the stock solution thus obtained, contained the following types of complex metal ions as the active ingredient.

Hydrogen ion: 0.5-1.6 mg Sodium ion: 1-135 mg Potassium ion: 1-27 mg Magnesium ion: 12-34 mg Calcium ion: 0.5-1.5 mg Manganese ion: 0.05-0.08 mg Copper ion: 0.05-0.28 mg Aluminum Ion: 0.5 to 11 mg Iron ion: 15 to 35 mg Hydrosulfate ion: 35 to 45 mg Sulfate ion: 485 to 815 mg Metasilicate ion: 3 to 6 mg Zinc ion: 0.01 to 0.03 mg

The first or second example obtained as described above
The stock solution (Shutokuishi leaching solution) of the example was blended in pure water at a predetermined weight% to obtain a trace amount of metal ion water. The trace amount of metal ion water thus obtained can change the neutral characteristics of pure water.
While pure water , which is not neutral water, has a large electrical conduction load resistance during silver ion electrolysis, the effective introduction of the metal ions contained in the above-mentioned minute amounts allows the electrical conduction load during silver ion electrolysis to be increased. The resistance decreases.

The content of Shotoku stone leachate in pure water is
It is preferably 0.03 to 0.10% by weight. That is, the undiluted solution of Example 1 or Example 2 obtained as described above was blended in pure water at a predetermined weight% to prepare several hundreds of samples, and comparative tests were conducted on sludge sedimentation speeds using a beaker. As a result, it was confirmed that the stock solution containing 0.03 to 0.10% by weight had an effect of remarkably promoting the sedimentation rate of sludge. As a result, blending the above-mentioned Shotoku stone leaching solution with respect to pure water within the range of 0.03 to 0.10% by weight improves the silver electrolysis value in the above-mentioned trace amount of metal ion water, and the conductive load during silver ion electrolysis It is presumed that it is in a preferable range because the resistance becomes small and the silver ion water according to the present invention can be efficiently produced.

Then, by using the above-mentioned trace metal ion water, the silver concentration is 0.5 to 5 ppm and the trace metal ion concentration is not more than 0.5 by the method shown in FIG. 1 or 2.
0001-0.05 ppm and pH 6.5-7.5 of silver ion water were obtained. The results of various tests using this silver ionized water as a test stock solution will be described below.

The test product was found to have the same antiseptic effect as the comparative product, and the user did not cause dermatitis or rash.
