There are disinfection water in the air. Where did you come from?Spontaneous

Hydrogen peroxide, if this name makes you feel unfamiliar, then its other name will definitely make you feel very familiar, that is, hydrogen peroxide.

We all know that hydrogen peroxide is a disinfection agent, and its disinfection effect is mainly achieved through its strong oxidation. The accu 'bacteria and various intestinal pathogenic bacteria we are familiar with can be easily killed by hydrogen peroxide. Therefore, hydrogen peroxide is widely used in environmental disinfection and wound disinfection. In addition to the medical field, there are many places in industrial production and daily life. Although the hydrogen peroxide is widely used, it is not very easy to make. Generally speaking, it is necessary to produce hydrogen peroxide. The common methods are electrolytic methods, isopropyl, and 蒽醌 methods.醌 醌. Obviously, the production of hydrogen peroxide requires voltage and catalysts.

The use of hydrogen peroxide is wide and demand is large, so there have been people internationally internationally studying the new production methods of hydrogen peroxide, and a research team at Stanford University accidentally discovered a phenomenon when studying this issue, that is, hydrogen peroxide is that hydrogen peroxide is that hydrogen peroxide is Can be formed spontaneously.

The research team found that water molecules in the air can spontaneously convert them into hydrogen peroxide. This sounds like nothing, because water is H2O, and hydrogen peroxide is H2O2. The two are worse than an oxygen atom, which seems to be easy to complete the conversion, but it is not so easy. Although there is only one oxygen atom between water and hydrogen peroxide, if you want to supplement this atom, it means that you must break the original co -price key before you can add a oxygen atom. With the participation of no voltage and catalyst, how can we break this co -price key?

Water molecules in the air are self -converted into hydrogen peroxide. It is conditional. This condition is that the volume of water droplets is small enough.

Studies have found that when the diameter of the water droplets in the air reaches less than 20 microns, the water can become spontaneous into hydrogen peroxide. What is 20 microns? The minimum length unit we can use in daily life is millimeter, and one micron is equal to one thousandth of millimeters, which is so small. Now the question is, why can water droplets be spontaneously transformed into hydrogen peroxide? This stems from a phenomenon called "contact". When the micro water droplets and the solid collide, the charge will "jump" between the liquid and the solid, so an unstable molecular fragment will be produced, which is active oxygen.

These unstable molecular fragments caused by collisions contain hydroxyl free radicals. They are triple electron reduction products. When they are paired, they can combine hydrogen peroxide.

The micro water droplets collide with the solid? Where is the solid? The air is full of dust, they are solid particles, so the collision between micro -water droplets and solids in the air occurs at all times, so hydrogen peroxide is naturally generated, but this naturally generated peroxidation The number of hydrogen is very small. The research report from Stanford University's research team caused a question when it came out. For example, some people questioned that the hydrogenangrotanate in the air must use potassium permanganate, but the team then explained that they used mass spectrometers to use mass spectrum spectrum Dharma detects hydrogen peroxide in the air.

There is a spontaneous formation of hydrogen peroxide in the air, that is, disinfection water, which is related to our lives? The relationship is really big.

As we know, in cold winter, people are always more likely to suffer from respiratory diseases represented by colds. Why? Because the weather is cold? These diseases are essentially caused by bacterial infections, and they are not directly related to hot and cold. Moreover, even if they stay at home without going out, it is still easier to catch a cold in winter than summer. Now we seem to have a more reasonable explanation about this issue, that is, the number of bacteria and viruses in winter air is higher than summer, and the reason is on the spontaneous formation of hydrogen peroxide. In winter, the air is dry, and the amount of micro -droplets in the air is small, which has reduced the number of hydrogen peroxide for spontaneous formation. The disinfection effect decreases, and there are naturally more germs.

In winter, because heating equipment is used, the air in the room is more dry, and the content of micro -water droplets and hydrogen peroxide in the air will be less. If you do not pay attention to ventilation, you will inevitably breed bacteria.

The above is the conclusion obtained by the research team of Stanford University. To a certain extent, it explains part of the relationship between seasonal and respiratory diseases. This reminds me of another problem, which is life. As we all know, the average life expectancy of people living in dry and cold areas should be significantly longer than those in the humid area. This may also have a certain relationship with the content of hydrogen peroxide in the air, because hydrogen peroxide is a strong oxidant, and the aging process of human aging process In essence, the oxidation process, so the high hydrogen peroxide content in the air may accelerate the aging of the human body to a certain extent.
