Magus Tech Chapter 889: Feeding the Abyss: Demon Yellow Cake
Genius remembers the address of this site in one second: (Apex Chinese), the fastest update! No ads! Garden of Eden.
Li Cha completed the first step of the preliminary extraction of uranium, and obtained a solution containing less impurities.
After finishing all this, Li Cha walked out of the laboratory and began his first rest in a long time.
"Wow!"
Take off the heavy chemical protective clothing, wash the whole body, add some food and salt water, and sleep for a while.
About an hour later, Li Cha opened his eyes on a bed in a room in the underground laboratory.
"Swipe!"
Quickly got up, put on a new chemical protective suit, replaced a new oxygen cylinder, and started the second step of uranium purification.
This time, Li Cha took out the specially prepared pale yellow translucent liquid from the warehouse.
The function of this liquid is to carry out special extraction.
Extraction, also known as solvent extraction, liquid-liquid extraction, and extraction, is based on the principle that the mixture is separated by virtue of the different solubility of the components in the system in the solvent.
To put it simply, because there is a certain gap in the solubility of a substance in two immiscible solvents, this characteristic can be used to transfer the substance from one solvent to another.
After that, the two immiscible liquids are separated by liquid separation, and a certain component in the mixture is also separated.
For these, Li Cha had fully considered these before the experiment, so he didn't hesitate at this time, took the container containing the extract, entered the laboratory, and then opened the lid and poured it into the reaction pool.
It can be seen that after pouring the extract, the extract and the original liquid in the reaction tank form two very obvious liquid levels, one up and one down.
Under the action of suction, the specific substances in the original solution of the reaction pool move towards the extraction solution and are cleaned up in a short time. .
Without a pause, Li Cha continued to be busy, using other methods to continuously operate the reaction pool, and continued to clean up the remaining impurities, so that the types of elements contained in the stock solution became less and less.
After half a day like this, except for uranium, there are very few other elements in the reaction pool.
The uranium element at this time exists in TBP, that is, in the tributyl phosphate solvent.
This is a colorless and transparent liquid, insoluble in water, has a certain degree of toxicity, and can exert a certain inhibitory effect on human plasma. When the human body intake exceeds the limit, it can cause dyspnea, convulsions, paralysis, lethargy and other symptoms.
In addition, this substance is irritating to the skin, and its vapor and smoke can cause damage to the eyes, mucous membranes and upper respiratory tract.
But at this time, Li Cha, who was wearing protective clothing and fully armed, did not have any worries, and continued to operate with confidence and boldness.
What he has to do at this time is back extraction.
As the name suggests, stripping and extraction are opposite to each other.
Their principles are the same, they are a substance with different solubility in two immiscible solvents, which allows the substance to transfer between the two solvents.
However, extraction generally involves the transfer of substances from an aqueous phase to an organic phase.
For example, that is to transfer a substance from hydrochloric acid (water phase) to oil (organic phase).
Back extraction is the transfer of substances from the organic phase to the aqueous phase.
TBP is tributyl phosphate solvent, which is the organic phase. At this time, Li Cha is going to transfer the uranium element out of it, and the stripping agent used is dilute nitric acid.
"Wow!"
Open the container, pour a large amount of dilute nitric acid into the reaction pool, the reaction proceeds rapidly, and the uranium element keeps leaving from the tributyl phosphate solvent and enters the dilute nitric acid.
After a while, the transfer of uranium was completed, and the tributyl phosphate solvent in the organic phase was cleaned up, leaving the uranium-containing nitric acid solution in the aqueous phase.
But this is not the end.
Following that, Li Cha added the last substance-magnesium oxide into the reaction pool.
Magnesium oxide (MgO) is an oxide of magnesium, which appears as a white solid at room temperature.
Because this substance exists in nature in the form of periclase, it is relatively easy to obtain. At this time, Richard has a lot of reserves in his hands.
Considering that magnesium oxide is exposed to the air, it is easy to absorb moisture and carbon dioxide and gradually become basic magnesium carbonate, resulting in deterioration. Li Cha carefully stored the magnesium oxide that was ground into powder in a dry barrel-shaped glass container.
At this time, Li Cha took out the magnesium oxide powder in the glass container from the warehouse, quickly opened the lid of the container, and added it to the reaction pool.
The magnesium oxide enters the liquid and reacts rapidly with the nitric acid contained in it, which also affects the uranium contained in it.
Visible to the naked eye, as time goes by, precipitation begins to form.
Look carefully, it is a kind of golden yellow precipitation, like gold.
Glittering and shiny, it seems to exude a dazzling luster, with a kind of precious atmosphere.
Its ingredient is magnesium diuranate, and another name is... yellow cake.
Yellow cake!
Yes, yellow cake!
The second step of purification of uranium is completed!
…
After the second step was completed, Li Cha didn't stop and did a lot of tedious finishing work.
A few hours later, the finishing touches were completely over, all the precipitates in the reaction pool were taken out and passed the test successfully, and all this was considered to be over.
The final result is that a special metal barrel is filled with almost half of the yellow cake—this is the product of the second step of purification of uranium elements—and in order to obtain this half barrel of products, almost a full barrel Five hundred barrels of mineral powder were successively put into the reaction pool.
In other words, the ratio of raw materials to finished products is almost 1000:1.
Considering the other substances added in the process, this number is even more exaggerated.
The difficulty of preparing yellow cakes can be seen from this.
But anyway, it was prepared successfully.
…
"Hoo—"
In the protective suit, Li Cha let out a breath slowly. Through the protective gloves, he touched the yellow cake in the metal bucket with his hand, and his eyes sparkled. He knew very well in his heart that the successful preparation of the yellow cake had greatly improved his nuclear weapons research and manufacturing plan.
After all, this is yellow cake.
This is a real product of the nuclear industry.
Only when you get this can you start in the nuclear field.
On the other hand, getting this is considered a successful start in the nuclear field.
Continue to develop, and step by step you will gain the right to speak to influence the entire world~IndoMTL.com~ This is a qualification and a threat.
So, on the earth, the circulation of yellow cakes is closely monitored by major powers. In some movies, yellow cakes also often become key items for terrorist organizations to compete for.
Li Cha pursed his lips.
The preparation of yellow cake, for him, the most important meaning is that it can be seen as a sign of success in a small stage.
After testing at this time, he has determined that the uranium content in the yellow cake is almost 60%.
This value is low. Under normal circumstances, the normal yellowcake uranium content is 75%.
However, considering that there were many unavoidable mistakes in the first experiment, this value is acceptable. Then, as the experiment process is repeated and fine-tuned, the value will gradually increase, and finally reach the ideal 75%.
At that time, you can proceed to the next third and fourth steps.
There is still a long way to go, but at this moment he is very confident to reach the end.
He is looking forward to that day.
"I'm looking forward to it..." Li Cha murmured in his protective suit.
At this moment, he felt that what he was holding was not a simple chemical raw material, but more like feeding the devil in the abyss. As he continues to prepare, as he continues to feed, eventually a terrifying big demon will crawl out of the abyss, with a roar that can shake the sky, and its power can destroy the world.
Of course, he believed that, no matter what, the chain around the neck of this terrifying great demon was firmly in his hands.
Because this terrifying big demon was created by him bit by bit.
In a sense, this terrifying big demon is actually himself, the **** he has always hidden in his body.
At that time, whether this great demon will be used for destruction or creation will all depend on his choice.
And now he hopes that the situation will not be too bad by then, and that this world can keep a bit of beauty for him.
Hope...
