[Knowledge technology]: Since then, there have been reports of so-called alkaline electrolyzed water produced by electrolysis of water, which has been shown to have medical effects such as inhibition / poor diarrhea and diarrhea. Although the main reason is considered to be the electrolyzed water Contains the original components of the disease in the form of cations, but the above-mentioned elimination of the body molecule is $, 丨 n The body molecule is oxidized, which makes the organism "know injury", so it is judged that this is the main cause of illness. High organism = its Ming Zhe et al. Once based on the low reduction potential water can raise the acidity of the redox potential even ^ > Ⅱ @ ^ f, the special 与 ρΗ value and only the xixi,) As for the alkaline raw water, it can be used as a companion.

In addition, it is used by the present invention. ;: The nature can be used as the reduction of washing water or oxidizing exhaust gas. In addition, the method of adjusting the water quality standard of tap water to a range of ρΗ 5. 8 8. 6 is not particularly limited. For example, acid can be added to the water towel or Surface gas to adjust. water,? There are no particular restrictions on the type of f in the second category. Examples include taps, Γ = v, steamed Germans, or soft water.

颧 点 丈 °: Use in combination on U. Among them, from the point of easy adjustment of pH =, it is based on the use of at least one kind of water in the group consisting of selected pure water, purified water, destilled water, and right water.

It can be removed using, for example, a cation exchange resin. Ion addition (7) Alternatively, it may be added to the raw water (electrolyzed water) before and / or after electrolysis. , 'It belongs to J. It belongs to ㈣, π is commanded to the knife edge 1, and the inverse λτ is not set to a low potential so that the redox potential can be maintained for a long time.The addition of the knife or hunting metal ions can give it The so-called ambiguity „maintains the preservability of the given characteristics. The month『 Chang will use the reducing electrolyzed water produced by the present invention to explain in detail based on the electrolytic Chinese formula. First of all, it has a pH below the specified value and a value of 0RP. Basic reaction on the reduction side (cathode side) 'The basic reaction formula is shown in the following formula (9). In terms of metal ions, calcium ions or magnesium ions, etc. Examples of Hji electrolyzed water include, for example, sodium ions and potassium ions. , 2H20 + 2e ~ — H2 + 20H will be converted to the Nernst equation as follows: E = E. + (2 · 3RT / 2F) l0g {H20P / {H2} o {0H-} 2 However, E is the redox potential, Eq is the standard redox potential, τ = 7 temperature (K), R is the gas constant (= 8.3), F is the Faraday constant ^ 96485), {X } Is the activity of the substance X. α The activity of the substance 丨 X}, in which the concentration of the substance is [X] and the activity coefficient is X Rishou ' Table {X} = α χ · [χ]. In addition, if the dissociation of water is represented by K 490,445 5. Explanation of the invention (5) constant, since K = [Η +] · [0Η _] / [Η20] = 1 · 8 X 1〇_16, so substituting it into the above formula (1) becomes as shown below: Ε = Ε〇 + 0 · 0295 log {Η20} 2 / {Η2} Μ0Η-} 2 = Ε〇 + 0.0295 log α12 [Η20] 2 / α2 [Η2] · α32 [〇Η-] 2 = Ε〇 + 0 · 059 log [H +]-〇 · 059 log (l · 8X1 0_16) -0.0259 1 og [Η2] + 0. 0 2 5 9 log (αλ2 / α2 α32) = Ε〇-0. 0 5 9 · pH + 0.9929-0. 〇259 1 og [Η2] +0.029 5 1 〇g («I2 / 〇ί2 α32) Here, if EG + (K 929-0 · 0 259 l0g [H2] + (K02591og (α '/ α2 α32) = Β (constant)), the above formula can be arranged as follows:

—59 · pH B, (see Figure 1), so according to the above formula, the relationship between the M potentials can be expressed linearly, and the redox potential can be increased. It can be known that if it decreases (acid side), it is not particularly limited. If T energy is used, the amount of dissolved oxygen in the electrolyzed water is reduced and the reduction potential is as low as possible. In Zhao, it is better to be close to Oppm, and the oxygen levels are all as described above. If the amount of dissolved oxygen and the suppression of oxidation in a redox body are suppressed, it is highly anticipated that the generation of active forces caused by active oxygen is suppressed.

In addition, ^ generated using the present invention is less favorable.

= The above Nernst equation shows that… the original potential is high, so it is usually on the positive side; and == = the unit is low, so it is usually on the negative side. * In the above relationship, if U and the original potential are set to -300mV, the original redox potential of the water on the other side of the test side is originally low, so it is sufficient to change it a little, but the acid side with low pH is sufficient. Water must have a large change: Dagger: Therefore, if you want to reduce it to the same redox, the degree of change between the acidic side and the alkaline side will be different. According to the present invention, since electrolyzed water having weak acidity to slightly neutral ^ can be used to produce reducing electrolyzed water having a redox potential below a predetermined value, the degree of change of the redox potential before and after electrolysis Becomes very big. As mentioned above, if reducing electrolyzed water having a large degree of redox potential change before and after the electrolysis and having a low redox potential is used, when the reducing electrolyzed water is left standing for a long time, its redox potential rises, In the case of a rise of 0mV ~ 100mV, as long as a small amount of hydroxide (such as sodium hydroxide, potassium hydroxide, calcium hydroxide, etc.) is added, it can be restored to the original in a short time. The phenomenon of redox potential was also discovered by the present inventors. In addition, in the case where there is a low oxygen + reduction potential and the degree of redox potential change before and after electrolysis is small (if it is equivalent to alkaline electrolytic water according to Figure 1), even the addition of hydroxides, etc. Either it takes a long time to return to the original redox potential, or it becomes difficult to recover. This phenomenon has also been confirmed by the inventors and others. [Simplified description of the diagram]
