How many people have been cheated by the hydrogen-rich water cup?
I believe that the friends who can search this question must be faced with the following situations:
1. What should I do if the elderly at home want to buy two or three thousand hydrogen-rich water cups and two or three thousand hydrogen-rich water machines?
2. Does a friend send a hydrogen-rich water cup have any effect? Use it again if you have it.
3. I always hear about this thing on the Internet. What is it? Should I buy it? How to buy?
Since the whirlwind of Japanese hydrogen-rich water cup was blown to China, with the continuous occurrence of hydrogen legendary events, domestic hydrogen-rich water products have increased.
many people have benefited, but many people will still ask, is the hydrogen-rich water cup true or false? First, let's learn about hydrogen medicine.
To answer the question "Is hydrogen-rich water a scam?", we must first understand the origin, functional basis and health-preserving principle of hydrogen-rich water.
The concept of hydrogen-rich water actually originated from Japanese plain water, which is hydrogen-containing water in Japan. As soon as this concept arrived in China, it was naturally called hydrogen-rich water.
In p>27, Professor Naruto Ota of Japan Medical University published a paper "Anti-oxidation Treatment of Oxygen Free Radicals by Selective Reduction of Cytotoxicity by Hydrogen" in the world-famous journal Nature Medicine, and found that hydrogen molecules can scavenge human free radicals and have a good therapeutic effect on aging and various chronic diseases caused by free radicals.
learn from Shaanxi science and technology news: is health "hydrogen" so important? If this paper by Professor Naruto Ota of Japan Medical University in 27 is false, then hydrogen-rich water is a scam, otherwise hydrogen-rich water is true.
Because hydrogen molecule is the smallest molecule in the world, although its solubility in water is not high, its permeability is extremely strong.
that is to say, although the solubility of hydrogen is low, there are a lot of hydrogen molecules in hydrogen-rich water. By drinking hydrogen-rich water, hydrogen molecules can be quickly absorbed by the human body, and even hydrogen molecules can directly enter the nucleus.
In fact, since the publication of this article, it has aroused great concern in international academic circles, and it has been quoted more than 5 times.
Many scholars from Japan, China, the United States and other countries have conducted extensive research on the evaluation of the therapeutic effects of various diseases, such as breathing hydrogen, drinking hydrogen water and injecting hydrogen saline. Animal models and clinical studies have proved that hydrogen has an auxiliary therapeutic effect on various diseases and injuries, and a new field of hydrogen medicine has been established.
According to incomplete statistics, there are more than 1, scholars engaged in hydrogen medical research in China
Nearly 1 academicians from the two academies participated in hydrogen medical research, including academicians Hou Yunde, Zhong Nanshan and Wang Zhenyi, as well as scientists such as Professor Sun Xuejun from the Second Military Medical University, Professor Xu Kecheng from the General Hospital of Guangzhou Fuda Cancer Hospital, Professor Yao Dingshan from Shanghai Institute of Technical Physics of Chinese Academy of Sciences and Professor Liu Jian from Xi 'an Jiaotong University.
Since p>213, there have been more than 8 national natural science foundation projects related to hydrogen medicine in China, and representative academic institutions have been established one after another:
More than 1 laboratories of Naval Medical University have carried out research on hydrogen brine to treat many important diseases;
The Hydrogen Science Research Center of Shanghai Jiaotong University conducts research related to medicine and agriculture;

Professor Sun Xuejun at a media conference. The interview said:
"From a social point of view, I dare not say that its discovery can be compared with the historical position of penicillin in that year, because penicillin can be immediately cured. The role of hydrogen molecules is more in conditioning, prevention and relief, and it is not excluded that a few patients can achieve the goal of radical cure only with hydrogen water.
Therefore, its future prospects are more inclined to chronic diseases that are difficult to cure, delaying aging and promoting health, but this is significant enough, and it will affect the whole medical field. "
So, if hydrogen-rich water is deceptive, why are there so many experts and scholars studying it?
So how do you choose the hydrogen-rich water cups with a wide variety? How to buy a hydrogen-rich water cup is the most reliable? Water and hydrogen remind everyone to remember one sentence: you get what you pay for.
how to choose a hydrogen-rich water cup?
The strategy is as follows
For Xiaobai, a hydrogen-rich water cup, he wants to buy a water cup, but he is often at a loss when faced with various hydrogen water cup products in the market, and he doesn't know how to choose.
Today, I'd like to share some knowledge about hydrogen-rich water cups in the market. I suggest you have a look at them before buying them to avoid being cheated!
first, the hydrogen-rich water is good, but it doesn't mean that the hydrogen-rich water cup is good!
Many people buy hydrogen cups, naturally because they take a fancy to the healthy conditioning effect of hydrogen molecules in hydrogen-rich water prepared by the cups.
you can't just look at the glass with a full sense of technology or the "face value" of the glass!
I want to tell people who want to buy hydrogen-rich water cups that they must remember this sentence: hydrogen-rich water is good, but hydrogen-rich water cups are not necessarily good.
apart from the concentration of hydrogen water prepared by water cups, water quality safety is very important.
after all, no matter how good hydrogen water is, it contains non-hydrogen derived products such as ozone and hypochlorite, and the precipitation of heavy metals. Do you dare to drink it?
most of the cheap hydrogen-rich water cups in the market adopt the solution of carrier electrolysis, and even more, two stainless steel sheets are directly used as the anode and cathode, so that the anode of this product will be completely oxidized in a few times, which will not only stop producing hydrogen, but also pollute the water source and bring health risks to human body.
the biggest feature of this kind of cups is that the bubbles are smoky or similar to milk. Because of the low electrolysis efficiency, large bubbles are produced, so they look white, and some have unpleasant odor.
Such cups are often low in hydrogen concentration. Many consumers who don't know anything but that hydrogen-rich water is good blindly and impulsively go online to find hydrogen-rich water cups. They are also complacent and feel that they have made a lot of money, but they may have been cheated.
How to distinguish the quality of hydrogen water cups? Apart from tasting the prepared hydrogen water with or without peculiar smell, here is a very simple method to teach you!
that is, buy a TDS (total dissolved solids) test pen (very cheap, about tens of yuan each, Taobao can buy it), fill a hydrogen cup with water (pure water or mineral water), and measure and record the TDS concentration of raw water.
don't cover the cup, then press the switch for 2 consecutive times to produce hydrogen, and then check the TDS concentration. If it is a good hydrogen cup, this value should not increase.
If the increase is relatively large, it means that there are a lot of solids in the water, which may be heavy metals precipitated in the process of cup electrolysis, which are harmful to human body and are not recommended for long-term use.
2. Classification of hydrogen production principles of hydrogen-rich water cups
At present, hydrogen-rich water cups on the market can be roughly divided into these three principles:
1. Entry-level hydrogen-rich water cups: chemical methods are generally used to produce hydrogen, which is generally the principle that metallic magnesium is used to make minerals with magnesium as the main component through a process, and magnesium reacts with water to generate hydrogen.
equation: Mg+2H2O=Mg(OH)2+H2↑ slowly reacts to generate hydrogen, and if hot water is used, the reaction will be strengthened.
Advantages: The hydrogen-rich water cup based on this principle has simple process and low cost.
defect: magnesium will be used up, so the filter element needs to be changed irregularly.
Moreover, this method of hydrogen production will produce magnesium ions, which are needed by the body, but a large number of magnesium ions are absorbed by the human body, which increases the complexity of the problem.
In addition, people need to drink a lot of hydrogen water in this kind of water cup for hydrogen production, and the function of hydrogen is only shown.
2. Universal hydrogen-rich water cup: common electrolysis method
This is adopted by most manufacturers of hydrogen-rich water cups at present. Platinum electrodes are placed in water at the same time, and hydrogen and oxygen are simultaneously generated and discharged into water during electrolysis.
electrode reaction formula: anode: 4oh-4e-= O2 ↑+2h2o, cathode: 4H++4e-=2H2↑
But the anode still has two side reactions, one of which is ozone generation: 3H2O-6e-=O3+6H+
The other side reaction is chlorine generation: 2cl-
Many consumers find that Jiangtian plain water cup is not suitable for China, and it will have an odor when used in China, which is ozone and residual chlorine.
in the final analysis, the reason is that tap water in Japan can be directly drunk, and there is no heavy metal and other organic pollutants, and there will be no residual chlorine.
In China, chlorine is added to the tap water for sterilization, and the chlorine content of chlorine-containing tap water will increase more than five times after electrolysis.
there is no way to avoid ozone.
Therefore, this universal hydrogen-rich water cup generally contains mineral particles to improve the taste, and some of them can partially absorb residual chlorine and ozone.
If pure water is used for electrolysis, the residual chlorine and ozone will be correspondingly reduced. However, many cups in the market which adopt the universal electrolysis method can't produce hydrogen with pure water or the hydrogen production capacity is greatly weakened, because the conductivity of pure water is very poor. If distilled water or deionized water is used, this cup won't work at all.
advantages: low cost and easy popularization.
defect: the problem of residual chlorine and ozone cannot be completely solved. Low threshold, numerous manufacturers and uneven quality.
3. High-end hydrogen-rich water cup: SPE proton membrane, pure water electrolysis, hydrogen-oxygen separation
Hydrogen-oxygen separation type water cup realizes complete hydrogen-oxygen separation through SPE proton membrane electrolysis technology, and the hydrogen production equipment at the lower part is equipped with an exhaust hole to exhaust the gas generated in the process of hydrogen production by hydrogen-rich water cup electrolysis, thereby improving the hydrogen concentration in water and enhancing the performance of hydrogen water on human body.
The specific hydrogen production process is as follows:
Proton exchange membrane is adopted, and electrocatalyst particles are directly attached to the membrane to form a membrane-electrode group. Membrane-electrode assembly is to embed active electrodes (catalytic substances) on both sides of solid polymer electrolyte membrane, allowing only protons and water to pass through.
during hydrogen production, the electrolytic reaction of water is carried out on the membrane-electrode which acts as a diaphragm and an electrode.
water undergoes an electrolytic reaction at the anode of the power supply, generating hydrogen and oxygen, in which hydrogen will become hydrogen ions due to the loss of electrons at the anode, which can reach the cathode through the proton membrane in the form of hydration, while oxygen cannot pass through and can only be discharged.
after hydrogen ions reach the cathode of the power supply, electrons obtained from the cathode recombine to form hydrogen, oxygen is discharged from the bottom, and hydrogen with high purity is injected into water.
Advantages: no residual chlorine and ozone are generated, and the generated hydrogen has high purity and high hydrogen-water concentration.
Disadvantages: Only a few foreign companies can produce SPE electrolyte membrane, such as DuPont, Dow, etc. Many parts of electrolytic cell are expensive, so the cost is high, and the price of hydrogen-rich water cup is not cheap.
Third, pay attention to distinguish between true and false hydrogen-rich water cups!
when many people choose hydrogen cups, they give priority to the products with high hydrogen production concentration.
indeed, it is generally believed in the industry that the relationship between hydrogen concentration and the effect is positively correlated, in other words, the higher the hydrogen concentration, the stronger the effect on human health.
for the opinion that the higher the concentration of hydrogen in water, the stronger the effect. The industry follows that hydrogen is relatively safe, and increasing the concentration can maximize the pursuit of the ideal effect.
However, there is a certain limit to the amount that each person can drink at a time, so only by increasing the hydrogen concentration in water can the hydrogen concentration in human blood be effectively increased.
at normal temperature and pressure, the saturated solubility of hydrogen in the laboratory is 1.58mg/L, which is what we often hear: 1.58ppm=158ppb.
in real life, it is difficult to reach saturation.
of course, the hydrogen concentration can be made very high through special processes, but this requires advanced hardware and technology.
The more effective measure to improve the hydrogen concentration in water is "hydrogen-oxygen separation", in which the gas is separated first, and then the gas-liquid mixing technology is used to maximize the dissolved amount of hydrogen in water.
this technology is also the technology used in the high-end hydrogen-rich water cup for hydrogen-oxygen separation mentioned above.
Those cheap hydrogen-rich water cups, which say that the hydrogen concentration can reach or even exceed 158ppb, are unreliable. Please choose carefully.
well, today's popular science time is over. Advise everyone, for the sake of health, don't be greedy for cheap, cheap goods are not good, and this is always the reason!
Finally, I would like to repeat that before buying a hydrogen-rich water cup, you must know more about relevant professional knowledge. I believe you can definitely buy a satisfactory hydrogen-rich water cup!
