Abstract

PROBLEM TO BE SOLVED: To numerically and objectively judge the degree of activity of water. SOLUTION: An anode plate 4 is inserted into A chamber of an electrolytic bath 1 consisting of two chambers separated by an electrolytic diaphragm 2, while a cathode plate 5 is inserted into B chamber, and water 3 to be measured is filled into A, B chambers, respectively. The poles each are energized with a fixed current from a DC power source 7 through a timer 6 for a specified time. Then, after the water 3 to be measured is sufficiently agitated, the hydrogen ion concentration of water is detected by a detector 10. The detected values are taken out by a concentration-difference indicating device 11 and the values are regarded as the activity of the water.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION When water having a specific function is called functional water, the functional water is collectively called activated water. Therefore, there is no clear definition of activated water, but in general terms, activated water can be understood as water having higher activity than ordinary water, and application development is now being promoted in various fields. In any case, the significance of measuring the degree of the activated water is significant in that useful effects for the respective purposes can be expected without using a special chemical.

2. Description of the Related Art Activating means of known functional water is roughly classified into a magnetic treatment method, an electron field treatment method, an electrolysis treatment method and the like. In any case, the measurement procedure for objectively judging the degree of activity is as follows. not exist.

[0003]

Even if water is activated, it is not always clear on what basis the water is activated. The measure which the inventor has reached is to electrolyze water and observe the decomposition rate, and use this rate as a standard for activation. Specifically, a certain amount of substance is given to water, and the amount of ions formed by electrolysis of the water before and after that is measured. At that time, if there is a difference, the difference may be used as the activation difference.

[0004]

SUMMARY OF THE INVENTION A water tank is separated into two chambers through a material such as a diaphragm that allows only ions to pass through. An electrode for supplying a current to each chamber is prepared. Both chambers contain the same aqueous solution to be measured. After that, the electrode of one room is made positive and the other electrode is made negative for a certain time,
After applying a constant current, the hydrogen ion concentration of both solutions is measured. The measured ion concentration is calculated, and the value difference is defined as the activity of water. Thus, the activity of water can be stably specified by means with a simple configuration.

[0005]

In FIG. 1, an anode plate 4 is inserted into a room A of an electrolysis vessel 1 composed of two chambers separated by an electrolytic diaphragm 2, and a cathode plate 5 is inserted into a room B to cover each of the rooms A and B. Add measurement water 3. A constant current is supplied to each pole from the DC power source via the timer 6 for a predetermined time. Next, after the water to be measured 3 is sufficiently stirred, the respective hydrogen ion concentrations are detected by the detector 10 using the hydrogen ion detection electrodes 8 and 9. The detected value is taken out by a concentration difference calculator (concentration difference display) 11, and this value is used as it is as the value of water activity.

[0006]

According to the disclosed method and apparatus of the present invention, it is possible to measure the water activity which enables objective evaluation irrespective of simple constitutional means. The present invention has an inventive step in that the degree of activity of functional water is quantified from the conventional idea grasp.

Claims (2)

[Claims] In the production of functional water, when a certain physical quantity is given to water and the water before and after the water is electrolyzed and the amount of ions formed is measured, if there is a difference in the amount of ions between the two, the difference value is determined. A method for determining the activity level of the functional water based on the difference in the electrolysis rate of the water as the difference in the activation. 2. In the measurement of the activity of functional water, one water tank is separated into two chambers through an object such as a diaphragm that allows only ions to permeate, and the same aqueous solution to be measured is inserted into each of the two chambers and inserted into each chamber. After applying a predetermined current for a certain period of time with the electrode as an anode and the other electrode as a cathode, both hydrogen ion concentrations are measured. An activity measuring device for water, wherein the difference in the value at that time is immediately regarded as the activity.
