Example 1

The acidic water electrolytic cell according to the first embodiment of the present invention, as shown in Figure 1, is installed in the housing 100, the housing 100, the electrolysis is made of a material having a different polarity to supply power for electrolysis Having the same electrode as the first electrode 200 and the second electrode 300, and any one of these electrodes to increase the potential difference to obtain the acidic oxidation water or acidic reduced water.

In particular, the acidic water electrolytic cell according to the present invention configures the

filling chambers

110a and 110b by using the ion exchange membrane 111 inside the housing 100 so that the electrolyzed ions can be filled in a predetermined space.

Hereinafter, this configuration will be described in more detail.

The housing 100 is an electrolytic cell body for causing electrolysis by receiving a certain amount of water (raw water) therein.

The housing 100 is formed in a hollow hollow shape, and is provided with an ion exchange membrane 111 to separate the electrolyzed ions. The ion exchange membrane 111 partitions the inside of the housing 100 into at least two

filling chambers

110a and 110b. In the preferred embodiment of the present invention is described as being separated into two, but may be configured to be separated more than this. In a preferred embodiment of the present invention, such an ion exchange membrane may be used a fluorine-based catchon exchange membrane (Dupont Nafion 117).

Meanwhile, in each of the

filling chambers

110a and 110b, inlets 112a and 113a for receiving raw water (water) for electrolysis and

outlets

112b and 113b for discharging the electrolyzed acidic water to the outside are formed. do.

Here, the

filling chambers

110a and 110b are described as being composed of two, but a plurality of compartments are divided by the ion exchange membrane 111 and may be configured in a form connected in parallel.

The first electrode 200 is installed in any one of the filling chambers 110a. In this case, the first electrode 200 secures a filling space having a predetermined size between the ion exchange membrane 111.

To this end, the first electrode 200 is installed in the filling chamber 110a such that the gap W1 with the ion exchange membrane 111 is 0.1 to 2.0 mm. This is because if the gap W1 becomes wider than this, the electrical resolution with the second electrode 300, which will be described later, is reduced.

In the preferred embodiment of the present invention, when the first electrode 200 is mounted in the housing 100 having two or more filling chambers, the first electrode 200 is mounted in the filling chamber provided at the outermost side.

The second electrode 300 has a different polarity from that of the first electrode 200 and is installed in the other filling chamber 110b to be adjacent to the ion exchange membrane 111.

In this case, when a plurality of filling chambers 110b in which the second electrodes 300 are installed are provided, one second electrode 300 is provided for each filling chamber.

The third electrode 300 ′ has the same polarity as the second electrode 300 and is installed in the filling chamber 110b in which the second electrode 300 is installed.

In this case, the third electrode 300 'is spaced apart from the second electrode 300 by a predetermined gap W2. In this case, the gap W2 is formed to be 0.1 to 100.0 mm, and the gap W2 is used as a space for filling ions therebetween.

Meanwhile, in a preferred embodiment of the present invention, the above-described first to

third electrodes

200, 300, and 300 'may use a porous platinum electrode or a mesh platinum electrode.

[동작][action]

Referring to the operation of the acidic water electrolytic cell according to the present invention having the same configuration as in the first embodiment of the present invention as follows.

First, raw water is supplied to the housing 100 through the

inlets

112a and 113a. In this case, the raw water may be supplied through only one of the two

inlets

112a and 113a.

Next, an anode (+) is applied to the first electrode 200, and a cathode (−) is applied to the second electrode 300 and the third electrode 300 ′. Accordingly, as the electrolysis of raw water occurs, OH ⁻ is filled in the filling chamber 110a to which the anode is applied by the ion exchange membrane 111, and H ⁺ is filled in the other filling chamber 110b.

As such, when OH ⁻ and H ⁺ are filled in each of the filling

chambers

110a and 110b, current flows due to the potential difference between these ions. In particular, in the case of the charging chamber 110b in which the third electrode 300 'is installed, it is considered that some H ⁺ is converted into H or H ₂ due to the increase of the negative (-) ions.

The high potential difference resulting from the filling of ions can be useful for electrolyzing not only tap water but also electroconductive pure water (RO) or ultrapure water (DI) with low conductivity.

(1) Effect of hydrogen water on cathode side on retina of eye.

Retinal ischemia-reperfusion (IR) damage caused by a temporary increase in intraocular pressure (IOP) is known to cause free radicals and nerve cell damage.

IOP was raised for 60 minutes in mice to induce ischemia. During the ischemia reperfusion period, saline eye drops saturated with hydrogen gas of acidic hydrogen water according to the present invention were continuously administered.

As a result, the hydrogen concentration in the vitreous body was immediately vaporized and the IR-induced OH was reduced. Eye drops reduced retinal cell death and oxidative stress indicator-positive cell counts and inhibited retinal thickness reduction following activation of Muller glia, astrocytes and microglia. .

Eye drops restored more than 70% of retinal thickness.

(2) immediate-type allergic reactions

An immediate-type allergic reaction was observed from mice ingested with hydrogen water (1.0 ppm of hydrogen) obtained from the cathode side of the acidic water electrolytic cell of the present invention.

In rat RBL-2H3 mast cells, hydrogen inhibits FcεRI-associated Lyn phosphorylation and its downstream signal transduction (NADPH oxidase activity and decreases hydrogen peroxide production). Inhibited

(3) Measurement test of antioxidant power of hydrogen water obtained from cathode side

Four-week-old male ICR mice were acclimated for one week, followed by free feeding of feed and hydrogen water for 15 days, and the control group consumed tap water. Hydrogen water was replaced three times a day to prevent concentration decrease. After the end of the sample, mice were anesthetized with ether and blood was collected from the heart. The collected blood was isolated from the plasma containing anticoagulant.

Plasma total antioxidant activity was measured using a kit for measuring total antioxdant status of Randox Inc. (U. K.). The immobility time was measured during 6 minutes of forced swimming to investigate the effects of physical fitness. This measurement was performed by filling a circular cylinder (height: 25cm, diameter: 10cm) with 10cm depth of water at 23 ~ 25 ℃, and floating the mouse in a floating position with no head motion and floating for 4 minutes before the end. The time was measured.

After the forced swimming test, the mice were anesthetized with ether and blood was collected from the heart. The collected blood was centrifuged for 10 minutes at 3000 rpm at 4 ℃ to obtain a serum.

Serum blood urea nitrogen, creatin kinase, lactic dehydrogrnase, glucose and total protein (Autoanalyzer, Hitachi 747. Hitachi Japan) total protein) was measured. The measurements were analyzed by Student's t-test and expressed in M ± SEM.

Oxygen is an essential element for organisms in organic respiration, but active oxygen, which occurs when energy is incompletely reduced during metabolism, denatures and destroys macromolecules in the cell, destroying homeostasis and killing cells. Free radicals are produced by factors such as tobacco and soot, which damages biological components such as proteins, DNA, enzymes, and T-cells, causing various diseases, and especially attacking unsaturated fatty acids, which are components of biological membranes, to produce lipid peroxide. It is known to cause aging and adult disease.

After ingesting hydrogen water for 15 days in 5-week-old ICR mice, plasma was separated, and the total antioxidant status was measured and shown in [Table 3].

As a result, the total antioxidant power of the hydrogen water intake group was significantly increased by 18% compared to the control group ingesting tap water (P <0.05). The total antioxidant power of plasma can be considered as a representative value of the antioxidant power in the body, and the increase of total plasma antioxidant power means that the antioxidant power in the body is increased by the intake of hydrogen water. These results show that hydrogen water can increase the biological antioxidant power and protect the living body from various diseases and aging caused by various factors.

Forced swimming tests are used for antifatigue and endurance surveys. Five-week-old male ICR mice were ingested with hydrogen water for 15 days, followed by a forced swimming test to measure immobility time and blood biochemistry. Intake of hydrogen water significantly reduced the dead time in the forced swimming test of mice by 13% compared to the control group (see Table 4). This indicates that the intake of hydrogen water reduced antifreeze by increasing fatigue and endurance.
