DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of an electronic activity meter (pe meter) according to the present invention will be described below with reference to the drawings. First, the concept of the electronic activity pe described in the present embodiment will be described.
Recently, it has been found that strongly electrolyzed water obtained by electrolyzing water obtained by adding an electrolytic substance such as salt or potassium chloride to tap water has a strong bactericidal action, and is used in various fields. This strongly electrolyzed water is strongly acidic water with a pH value of about 2.5, which represents acidity / alkalinity, and this pH is about 11.5.
There is strong alkaline water, and it is used for disinfection in hospitals or for disinfection of pathogens transmitted to vegetables or fruit trees in place of pesticides in order to avoid the adverse effects of pesticides in the agricultural field.

Will be displayed directly on.

The principle of measuring the electron activity according to this embodiment will be described below. First, the electron activity pe of the electron e − in the sample water 2 is given by the following equation (1). pe = -log αe-=-log [e-] · γe ······· αe-: electron activity, γe: electron e-activity coefficient

The electronic activity pe mentioned above is
Regarding the electron concentration [e-] that is active in the electrolytic aqueous solution, 1
It is the product of the activity coefficient of the electron e- multiplied by the logarithm with 0 as the base, and the minus sign is added. The electrolyzed water having a large value of pe is water having an extremely shortage of electrons.

When the concentration of electrons (e-) in the aqueous solution is low and it is considered to be in the "infinite dilution" state, γe≈
It becomes 1. In this case, pe is the electron concentration [e-] (mol / l)
By using pe = -log [e-] ... it can.

The measurement of the reference electrode potential based on the standard hydrogen electrode is as follows. Generally the electrode reaction of the hydrogen electrode in the ^{2H + + 2e- = H 2 ·} · · · · · · · · · · ························· Given by the formula. The standard hydrogen electrode potential in a standard condition of temperature 25 ° C and 1 atm is EH ⁰ = 0.00 volt ..... It is defined as ... The electrode potential E of the reference electrode 3 based on the standard hydrogen electrode is E = Eref−EH ⁰・ ・ ・ ・ ・ ・ ・ ・ ・ Given by the formula.

The measurement of pe using a reference electrode calibrated with a standard hydrogen electrode is as follows. That is, the reference electrode 3 and the indicator electrode 4 are immersed in the sample water 2 whose pe is to be measured, and the potential difference between the electrodes 3 and 4 is measured. EH = Eref−Eind ・ ・ ・ ・ ・ ・ ・ ・ The electronic activity pe is pe = ( F / 2.3RT) EH ... (F: Faraday's constant, R: Gas constant, T: Absolute (Temperature, Eref: reference electrode potential, Eind: indicator electrode potential) From this equation, pe can be obtained using the equation.

Explaining why such electrolyzed water having a large electron activity pe has a strong bactericidal activity, the pathogenic microorganisms to be sterilized include hepatitis B virus (HBV) and AIDS. There are viruses (HIV), Staphylococcus aureus (MRSA), Escherichia coli, Salmonella, Mycobacterium tuberculosis and the like. These viruses and bacteria are single-cell microorganisms surrounded by cell walls and have a size of about 1 to 1/100 microns. The viral mesh-like cell wall is dressed like armor, which is only found in bacteria and not in human cells. The virus itself cannot synthesize proteins. It consists of a living part to survive for a certain period of time, information for increasing the number of offspring, and nucleic acids having genetic factors, and has the property of proliferating in other living cells. The cell walls of these viruses or bacteria are much thinner than plant and human cell membranes.

The cell walls of these viruses or bacteria include
There is a so-called proton pump that pumps hydrogen ions out of the cell. For this reason, a difference in hydrogen ion concentration or distribution is formed inside and outside the cell wall, and a potential difference is generated, and the electric force due to this is converted into the active energy of virus or bacteria. This is called the proton driving force and is a basic form of energy acquisition common to all living things. About these things, Shinichi Aizawa, "When an atom turns into life" (Kobunsha, 1993)
Issuance).

The above-mentioned bacterium moves the flagella protruding from the cell wall to move like Brownian motion. The source of the energy to move the venous hair is the proton driving force. In addition, the potential difference between the inside and outside of the cell wall serves to keep life by taking in or pumping out ions such as sodium, potassium, and calcium into and out of the cell wall.

As described above, the root of the activity of viruses and bacteria is the electric force of hydrogen ions applied inside and outside the cell wall.
Moving around using this electrical power is evidence that the bacteria are alive. Except in special cases, cessation of movement means the killing of bacteria. When strong electrolyzed water with a high electron activity pe is applied to such viruses and bacteria,
Due to the electrical characteristics of the extremely lack of electrons (large pe) and excess hydrogen ions (small pH), the potential balance inside and outside the cell wall is completely disrupted, and the bacteria stop their movements in an instant. The strong electric force of high-pe sterilized water causes holes or ruptures in the cell walls of viruses and bacteria, causing the internal nuclei (DNA) to melt. In order to reliably judge the bactericidal action of strongly acidic electrolyzed water, the present invention uses the electron activity pe
By directly measuring, it becomes possible to easily determine the bactericidal property of the strongly acidic electrolyzed water.

[0026]

As described above, in the electronic activity meter (pe meter) according to the present invention, the potential difference detected between the reference electrode and the indicator electrode arranged in the test water is input to the conversion amplification circuit, After being converted and amplified, it is transmitted to an analog display to directly display the electron activity, and the potential difference detected between the reference electrode and the indicator electrode is detected, and at the same time, the temperature detector detects the temperature of the sample water. The temperature is corrected and simultaneously converted and amplified by the conversion and amplification circuit, and transmitted to the digital display through the AD conversion circuit to display the electron activity directly outside. Therefore, the sterilizing property of the generated electrolyzed water having high electron activity can be easily determined.

The sterilized water having a large value of the electron activity pe thus obtained has a great bactericidal effect by stopping the movement of viruses or bacteria in an instant due to the electrical characteristics of the extreme electron deficiency and hydrogen ion excess possessed by the sterilized water. Obtained, especially when used for agriculture, conventional disinfectants, since it does not remain in agricultural products like pesticides used as bactericides at all, safety in terms of food hygiene and the human body is perfect, Even when used for medical purposes, the strong electric force of highly active sterilizing water causes holes in the cell walls of viruses and bacteria,
Alternatively, rupture enhances the bactericidal action, and does not have a harmful effect on the plant or human body that is the host of the fungus like antibiotics and chemicals that are common bactericides, and there is no fear of side effects. Therefore, it is possible to obtain the effect that it can be used for bactericidal action in a wide range of fields such as medical care, veterinary and animal husbandry, food processing, environmental hygiene, home hygiene, kitchen cleaning.
