Han Peacock saw a few words, lithium, uranium, and selenium, so he said incredulously: "Don't sue me, he can extract these three trace elements from seawater." ”

Liu Wu nodded heavily and said: "The technicians under Satan can also refine these three trace elements from seawater, lithium and uranium I don't need to say more, the focus is on selenium, do you know what kind of substance it is?" ”

"Uranium doesn't matter anymore? It doesn't seem like any other element is as important as it, right? This thing is a strategic resource wherever it goes. Han Peacock said.

Liu Wu said: "We all know what uranium is for, and we know its importance, but do you know what selenium is for? ”

Han Peacock looked at Liu Fu and said: "It's just that you children who grew up in the city don't know what selenium is, but I'm from the countryside, and I may not know selenium, don't you know that selenium is rich?" ”

Liu Wu glanced at Zhou Meidao: "Look, it's boring, right?" As long as you ask him, he will give you the standard answer, this man will not give you a chance to show off. ”

Han Peacock smiled and said: "I'll give you a chance to show your face, selenium-rich land has nothing to do with selenium refining, okay, now you two women who haven't even seen farming, give me a lesson." ”

Liu Wu said: "Then I'll say something professional, and let you know a little bit of power, do you know what benefits selenium has for the human body?" ”

Han Peacock held his forehead: "Can you not challenge my IQ, just say it, don't ask, or I can't help but say it, and you said that you didn't give you a chance to show it." ”

"Do you really know?" Liu Fu was surprised and said, this is a medical problem. Even if someone pays attention to this, they will definitely not understand it too much.

Han Peacock began to roll his eyes: "I've been studying cancer for so long, do you think I know?" Don't say it, I'll tell you what I know, and then you'll have to find an opportunity to add it. ”

"I won't talk about the selenium-rich land you know, but if you are interested, they have conducted a lot of research in order to obtain selenium ore, and the by-products are various minerals. Ordinary ones don't say. The most important of these are uranium and lithium, uranium ore you know, but lithium ore is also a very important raw material.

Lithium is extremely versatile in the metallurgical industry. Take advantage of the fact that lithium reacts with oxygen, nitrogen and carbon dioxide. to eliminate air bubbles in the metal. The conductivity of copper is often greatly affected by the presence of impurities, but an appropriate amount of lithium is doped into copper. On the contrary, it can increase its electrical conductivity.

Lithium is added to the glass to make lithium glass, which has high strength and good toughness, smooth and dense surface, and low thermal expansion, so lithium glass is widely used as a phosphor screen for TVs.

In addition to these, lithium can also be regarded as a strategic resource, lithium hydride is the hydride of lithium, which is a colorless crystal, 1ooo grams of lithium hydride and water can release 28oo liters of hydrogen, which is equivalent to the hydrogen stored in a cylinder with a pressure of 15o atmosphere.

This will provide an attractive prospect of using hydrogen as a power source, and needless to say, you can definitely think that whether it is a rocket or a missile, if hydrogen is used as fuel, the degree is certainly not comparable to ordinary missiles, and of course, the range will also be greatly extended, which is extremely helpful for your missile strategy.

In addition to these, the most striking is that lithium as a fuel for thermonuclear reactions, was used as an explosive for hydrogen bombs, on June 17, 1967, China successfully exploded the first hydrogen bomb, loaded with deuterium (heavy hydrogen) lithium hydride, 1ooo grams of lithium deuteride is equivalent to 50,000 tons of explosives, 1o times more powerful than the atomic bomb. ”

"I really don't know this, this lithium is not the same as uranium, so what about plutonium? You haven't said that yet? Han Peacock said with a smile.

Liu Wu also smiled: "Whether you really don't know, or fake don't know, since you say so, I will treat you as if you really don't know, plutonium is impossible to mineralize in nature, plutonium is a radioactive element, and its longest half-life isotope is plutonium244 for 8o8o million years."

There are only some rare earth minerals in nature (due to the shorter half-life compared to the age of the earth, they are basically decayed), and the other isotope of zài in nature is plutonium-239, which has U238 to absorb natural neutron formation (due to the very low yield and very small content, only a small amount of Zài is stored in uranium ore), and the only way to obtain plutonium industrially is to use U238 to capture neutrons in reactors.

So, they have the technology to get uranium, they have a nuclear reactor, they get some plutonium, it shouldn't be difficult, that's where those two miniature nuclear bombs come from, what else do you want to know? ”

Han Peacock said: "Quantity, I want to know how many kilograms of these elements they can extract per year." ”

Liu Wu said: "It is enough to use, although there are very few of these elements in the seawater, but there are a lot of seawater, so although it is difficult to refine these things, if you want, the yield can be increased infinitely." ”

Han Peacock said directly: "Cost." ”

Liu Wu said: "You don't have to be so smart, right? In addition to selenium, refining uranium and lithium is a loss-making business, so the greater the production, the more you lose, which is why Satan can't make money with this technology.

Of course, there is another reason for safety, after all, these elements are very sensitive, and if they are known by the outside world, they will definitely be sanctioned, so these things are kept secret by Satan.

Even if he has the means to buy it from other places, he will not make a move, but waste time and money, refining from the sea, because this is the safest, and when he has the hole cards in his hand, he will naturally not be afraid of others knowing. ”

Han Peacock was a little surprised: "Extracting these things from seawater is the step-by-step separation method used, right?" In this way, the refining cost of these minerals should be about the same, why does refining selenium not lose money? ”

Liu Fu and Zhou Meiren laughed at the same time, and Zhou Meiren said: "Finally, there is something you don't know." ”

Liu Wu saw that Han Peacock was about to open his mouth, and he hurriedly said, "You don't need to say it, I said." ”

Zhou Meidao: "Let's talk about the benefits of selenium in selenium-rich land, so that Han Peacock can also have a long insight." ”

"Selenium has been recognized by the World Health Organization and has been hailed by scientists as the 'God of Vision Protection' and the 'King of Fighting Cancer'." Liu Fu looked at Han Peacock and said.

"The king of cancer?" Han Peacock really doesn't know this.

"Where is this? Selenium is known as the king of anti-cancer, the messenger of light, the patron saint of the heart, the natural enemy of liver disease, insulin in trace elements, and it can also detoxify, detoxify, antioxidant and anti-aging, gold in the male body, the gospel of skin diseases, and the angel in white of the gastrointestinal tract, how about it, I don't know, right? Liu Wu said.

Han Peacock saw the catkins gushing endlessly, and hurriedly stopped: "Let's not talk about the others, let's talk about how it fights cancer first?" ”

Liu Wu said: "Selenium is called the 'king of anti-cancer' in the human body's trace elements by scientists, after research, the level of blood selenium is closely related to the life of cancer, a large number of survey data show that in a region of food and soil, the level of selenium content is directly related to the incidence of cancer.

For example, if the food and soil of an area are high, the morbidity and mortality rate of cancer will be low, and conversely, the cancer morbidity and mortality rate in this area will be high. ”

Han Peacock said: "That's why Satan separates selenium from seawater?" How did I hear that selenium is a toxic substance, though? ”

"Selenium is a toxic element, excessive intake can cause poisoning, leading to detachment, liver damage, gastrointestinal diseases, nervous system abnormalities, etc., daily intake of selenium from diet and pills, if no more than 4oo micrograms is safe." Willow catkins said.

Han Peacock said: "Then you have to pay attention to it?" ”

Liu Wu said: "Of course, however, selenium is a thing, more in the body is not good, less is not good, in 1935, the medical community is now black 1 ong Jiang Ke County, a kind of endemic cardiomyopathy is prevalent, the cause is unknown, it is named 'gram, mountain disease'."

After investigating the water and soil in the disease area, scientists believe that the cause is caused by the lack of selenium in the local water and soil, and that the disease has disappeared in Keshan County and has not regenerated since 1982.

Surveys of other parts of the world have also shown that where the content of selenium in the body is low, the incidence of cardiovascular disease is high, especially for men, selenium is an essential trace element for the human body, and foods rich in selenium include seafood, nuts, meat, etc.

The vast area extending from the northeast to the southwest of China is a selenium-deficient zone, 67% of the population needs to supplement selenium, and the selenium content of people from the daily diet is about 1oo micrograms per day on average, so there are many "selenium-rich" foods and health products on the market, which are based on the important role of selenium. ”

Han Peacock nodded and said: "From this point of view, refining selenium from seawater should be able to return to its original value, but it seems that the effect of selenium can be amplified a little, right?" ”

Liu Fu said: "Of course, in addition to the above effects, if a piece of land is transformed with selenium to form the selenium-rich land you just mentioned, then the selenium-rich agricultural products produced on this land belong to the list of health care agricultural products along with colored agricultural products, green agricultural products, and weight loss agricultural products."

Not only that, selenium can also effectively stimulate the growth of crops, significantly improve crop resistance to stress, lodging resistance, improve the yield and quality, and at the same time can activate and improve the soil, improve soil fertility, eliminate chemical residues and pollution in the soil, in those green industrial bases, just useful. ”

"It's really good to use selenium to transform selenium-rich land, but you should know what I value, so you can talk about how this selenium can fight cancer." Han Peacock said.

Liu Wu said: "Even if it is anti-cancer, but I have nothing to do with cancer, you better think of a way to make cancer contagious!" It is important to know that after the cancer cells are separated from the body, they will die in a short period of time, and even if a person comes into contact with the cancer cells, there is a breach in the body and it will not be infected.
