Description

Detailed Description of the Invention

Industrial application fields

  The present invention relates to daily drinking water, health and health drinks, sports drinks, cooking water, food and drink for taste, water division for liquor, water for food processing, medical substances, medical substance generators and the like.

  A technique of electrolyzing water to produce water in the anode region and water produced in the cathode region separately and using them has been used for about 40 years. In the past, two generators, an anode and a cathode, were placed in a pumping-type container, and a diaphragm was placed between them to draw the solution produced in both regions, and the water on the cathode side was used for drinking. In other words, the amount of generation was small, and it took a long time to generate, so there were many inconveniences in use and it was only used by some users. The present inventor invented a water supply direct-coupled alkaline ionized water generator in 1972, 32 years ago, and then rapidly spread and saw today's success. Alkaline ion water generators widely used today include two water passages separated by a diaphragm, with a positive and negative electrode plates facing each other in parallel in a sealed resin electrolytic cell and a diaphragm placed between them. A large number of the water that forms and contacts the cathode and collects it for drinking is used. Thus, the Yin-Yang electrode plate is a titanium plate having a thickness of about 0.5 to 1.0 m / m 2 and a platinum plate having a thickness of about 0.5 to 1.0 μm. Many use membranes with pore sizes on the order of microns. The properties of the cathode water obtained from such a generator are called alkaline ionized water because it is weakly alkaline and reducible at pH = 7 to 11, ORP = 0 to −500 mV. It is called a water container. Alkaline ion water produced by a conventional water conditioner has the above-mentioned properties, and the initial value of water discharge (water sampling) is pH = 7 to 11, ORP = −0 to −500 mV, but this value is unstable. Decreases in a few minutes and falls in a few minutes. This is a major drawback in the use of alkaline ionized water, but another problem is that it is difficult to control the values of pH and ORP by freely selecting them. More specifically, as an example, when tap water in Tokyo is electrolyzed at a current of 2 amperes, alkaline ionized water having pH = 9 and ORP = −300 mV is obtained. At this time, it is impossible to produce water at pH = 10 and ORP = −300 mV, and water at pH = 9 and ORP = −400 mV. That is, in water obtained by electrolyzing the same raw water, if one of pH and ORP is determined, the other takes a dependently determined value. Changing this correlation is difficult with the prior art.

Problems to be solved by the invention

  The above-mentioned attenuation of physical properties of alkaline ionized water (changes in pH and ORP over time) is a major drawback in the use of alkaline ionized water, and there is a demand for the appearance of alkaline ionized water that can withstand long-term storage by strengthening buffering against time or the environment. It was. There has also been a demand for development of a technique for freely setting and controlling the value of the ORP with respect to a desired pH value. However, it was considered extremely difficult to meet this requirement.

Means to solve the problem

  In order to solve the above two problems, the present invention adds a reducing organic acid or the like. The addition of the organic acid or the like or an aqueous solution thereof to the raw water can be followed by electrolysis, or the addition of the organic acid or the like or the aqueous solution after electrolysis can achieve the purpose. Electrolysis by adding a reducing organic acid or the like to water or preparing by adding a reducing organic acid or the like to electrolytic cathodic water, that is, electrolytic alkaline water, has two effects. One is to adjust the pH of the produced water by a neutral reaction. The other is to increase the buffer capacity by making the produced water a conjugate solution of a weak acid and a strong base. Electrolytic alkaline water is usually used as an electron donor compared to chemical alkaline water (used in the sense of, for example, a solution obtained by simply dissolving NaOH in water without adding electron or proton transfer operations such as electrolytic operation). The nature of is powerful. This is natural from the electrolytic alkaline water production process. As a result, it exhibits a strong reducing action, and ORP expresses a negative high potential as an index. The ability to defend active oxygen attacks on organs and cells is extremely strong. We try to use this cathodic reduction power, but in order to increase the absolute value of ORP, which is an index of reducing ability, if the electrolysis is strengthened, the absolute value of ORP will increase, but at the same time the pH will increase and the allowable value, for example pH = 10.5 is often exceeded, which is a problem in drinking. At this time, when neutralizing with a normal acid to lower the pH, the negative ORP (reducing property) of the corner is lost, but neutralizing with an organic acid having a reducing power (for example, an organic acid exhibiting a silver mirror reaction) The pH can be lowered to the drinking zone without impairing the reducibility (ORP). In addition, the solution system produced as a result of this neutralization is a typical conjugate solution with a weak acid and a strong alkali, so that it has a strong buffering capacity and is strong against disturbance, and can extend the duration of pH and ORP.

この水を電解すると陰極領域には電気泳動によりＮａ＋が集まり陰極の陰電荷で中和して金属ナトリウムとして析出し周囲の水と反応して次式の変化をおこす。
（次式） Ｎａ＋ ＋ −電荷 → Ｎａ
Ｎａ ＋ Ｈ_２Ｏ → ＮａＯＨ ＋ １／２Ｈ_２↑
ＮａＯＨ → Ｎａ^＋ ＋ ＯＨ⁻
ここに生じたＮａ^＋及び前式のＮａ^＋と前式のＣ_６Ｈ_７Ｏ_６ ⁻とは強塩基と弱酸との共役関係にあり、また過剰に存在するＮａ^＋はＣ_６Ｈ_８Ｏ_６の更なる電離を促し共役ペアを形成するため相当強固な緩衝系をなす。尚この系は強アルカリと弱酸によるものであるから当然アルカリｐＨ緩衝系であり同時に陰極領域によるものであるから電子過剰型電子ドナー系である。還元性が強く活性酸素を中和してそのアタックから防衛する力がつよい。ＤＮＡの変異を防ぎ、癌や成人病の予防にもつながり長寿をもたらす。The above has mainly described the case where a reducing organic acid is added. Next, the case where a reducing organic acid salt such as an alkali metal is added will be described. In general, the pH of water used for drinking is 5.8 to 8.6, and the main role of acid-base equilibrium is Na ⁺ , K ⁺ , Ca ⁺⁺ Mg ⁺⁺ , Cl ⁻ , SO ₄ ⁻⁻ , CO ₃ ⁻⁻ , HCO ₃ ^−. Etc. In electrolytic ionic water, Na ⁺ and Cl ⁻ are particularly important. It can be said that both of them have a high content in potable water and a large transport number in the electrolysis operation. For example, when sodium ascorbate C ₆ H ₇ O ₆ Na (structural formula) is added to the raw water as a representative of the reducing organic acid salt, a part of it is ionized as shown in the following formula (1) and the other part is As the following formula (2) is hydrolyzed, charged particles (ions) increase, so that electrolysis is facilitated and weak alkalinity is exhibited.

When this water is electrolyzed, Na + is collected in the cathode region by electrophoresis, neutralized by the negative charge of the cathode, precipitated as metallic sodium, and reacts with the surrounding water to cause the change of the following formula.
(Formula) Na + +-Charge → Na
Na + H ₂ O → NaOH + 1 / 2H ₂ ↑
NaOH → Na ⁺ + OH ⁻
Occurs here Na ⁺ and Equation of Na ⁺ and previous formula _{C 6 H} 7 _O 6 ^- that there is a conjugate relationship with a strong base and a weak acid is also Na ⁺ present in excess _{C 6 H} 8 _O 6 This promotes further ionization and forms a conjugated pair, thus forming a considerably strong buffer system. Since this system is based on a strong alkali and a weak acid, it is naturally an alkaline pH buffer system, and at the same time, based on the cathode region, it is an electron excess electron donor system. It is highly reducing and has a strong ability to neutralize active oxygen and protect it from attacks. It prevents DNA mutations and prevents cancer and adult diseases, leading to longevity.

Action / Theory

The fact that drinking water produced in the cathode region by electrolyzing potable water has been recognized physiologically and has been proven empirically and theoretically for more than thirty years. Administratively, alkaline ionized water (originally called alkaline calcium ionized water) has been recognized as having a medical effect, and its production device has been approved as a medical device and is widely used. However, I must admit that there is an aspect that cannot be said to be sufficiently refined universally, and I am deeply impressed with the need to deepen research and raise the theory. In the first place, this theory (the theory of alkaline ionized water) is based on the fact that human body fluids are weakly alkaline and that Japanese people are prone to calcium deficiency. At present, the situation has changed and the discussion has changed regarding the acid-base balance of body fluids and the issue of calcium. Discussions on the physical properties of body fluids shifted to their reducing properties, ie, electron donor properties. This is because the concept of attack by active oxygen on the living body was introduced in the recent trend of adult disease epidemic and prevention measures, and the existence of SOD and the electron donor property of body fluids are effective for the defense. This is because the idea has risen and many related clinical trials have been shown. The present invention was invented for the purpose of providing alkali ion water having ideal physical properties and a technique for producing the same, as a result of pursuing a new way of alkali ion water in such a flow. .
When water is electrolyzed, the movement of ions occurs due to the action of the electric force (Coulomb force) acting between the charge of the charged particles (ions) of the substance dissolved and ionized in water and the negative and positive electrodes, and the positive and negative charges The ions that are charged to each other migrate toward the negative and positive electrodes that are attracted to each other, and cations (positive ions) are collected in the negative electrode region and anions (negative ions) are collected in the positive electrode region. At this time, since the moving speed of ions differs depending on each ion, not all ions are the same. The moving speed of ions varies depending on the mass, the amount of charged charges, the number of water molecules bonded to the ions (hydration number), and the like. The earliest are hydrogen ion H ⁺ , hydroxyl ion OH ^{− and the} like. In general, the movement speed (mobility) of ions is actually much slower than the theoretical value because of hydration water. Also, the amount of ions that share the electrolytic current naturally depends on the type of ion. Although the ratio is called transport number, the main role of ions dissolved in raw water is generally Na ⁺ and Cl ^{− as} described above, but organic acids and their salts added to improve the properties of alkaline ionized water are dissociated here. The amount involved in electrolysis is not large because the degree is low and the mobility is low. There are many parts that pass through the electrolytic cell without electrolysis and participate in the subsequent chemical reaction. As a result, this solution system provided various interesting phenomena. Hereinafter, the chemical formulas will be used in order.
First, consider the case where L ascorbic acid is added to the raw water. Numerical data are given in the examples. Although this acid is highly reducible, the degree of ionization is not high and the ion formula is large, so it is not affected by electrolysis so much, but remains in the cathode region despite being an anion and forms a conjugated system with Na ⁺ produced by electrolysis. Then, a part of the solution neutralizes with Na to lower the pH of the solution (because it is a cathode region, which is alkaline ionized water). On the other hand, the absolute value of the ORP increases when stimulated by a negative electric field. That is, the effect of increasing the reducing power can be achieved without increasing the pH. Next, it was confirmed that when potassium potassium tartrate (Rochelle salt) was added to the raw water for electrolysis, the pH buffering action increased more than the effect on the absolute value of ORP.
