Vol 2 Chapter 889: Feeding the Abyss: Devil's Yellow Cake

Genius remember the address of this site for one second: (Vertex Chinese), the fastest update! No ads! Eden.
Richard completed the first step of the preliminary extraction of uranium element, and got a solution with less impurities.
After doing this, Richard walked out of the laboratory and began his first break in so long.
"Wow!"
Take off the heavy chemical protective clothing, flush the whole body, add some food and saline, and take a little sleep.
About an hour later, Richard opened his eyes on the bed in a room in the underground laboratory.
"brush!"
Quickly got up, put on a new chemical protective suit, replaced a new oxygen cylinder, and began the second step of uranium purification.
This time, Richard took the light yellow translucent liquid that he had specially prepared from the warehouse.
The role 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 components in the system have different solubility in the solvent to separate the mixture.
Simply put, because there is a certain difference in the solubility of substances in two incompatible solvents, this feature can be used to transfer substances from one solvent to another.
Then, by liquid separation, the two immiscible liquids are separated, and a certain component of the mixture is separated.
For these, Richard had fully considered before the experiment, so he did not hesitate at this time, took the container with the extraction liquid, entered the laboratory, and then opened the lid and poured into the reaction cell.
It can be seen that after pouring the extraction liquid, the extraction liquid and the raw liquid in the reaction tank form two liquid levels that are extremely obvious, one by one.
The specific substance in the raw solution of the reaction tank moves toward the extraction liquid under the action of suction, and it is cleaned up in a short time. .
Without a pause, Richard continued to be busy, using other methods to continue to operate the reaction cell, and continued to clean up the remaining impurities, so that the original liquid contained fewer and fewer types of elements.
After half a day like this, except for the uranium element in the reaction cell, the rest of the elements are very few.
At this time, the uranium element exists in TBP, that is, in the solvent of tributyl phosphate.
This is a colorless and transparent liquid, which is insoluble in water, has certain toxicity, and can exert a certain inhibitory effect on human plasma. When the human body intake exceeds the limit, it can cause breathing difficulties, convulsions, paralysis, lethargy and other symptoms.
In addition, this substance has a stimulating effect on the skin. Vapor and smoke can damage the eyes, mucous membranes and upper respiratory tract.
However, at this time, Richard, who was wearing a protective suit and fully armed, did not have any worries and continued to operate with confidence.
What he is doing at this time is back extraction.
As the name implies, back extraction and extraction are opposed to each other.
The principle is the same, they are all a kind of substance, there are differences in solubility in two incompatible solvents, so that the substance is transferred in the two solvents.
However, extraction generally transfers substances from the aqueous phase to the organic phase.
For example, it is to transfer a substance from hydrochloric acid (aqueous phase) to oil (organic phase).
Back extraction is the transfer of substances from the organic phase to the aqueous phase.
TBP, the solvent of tributyl phosphate, is the organic phase. At this time, Richard is preparing to transfer uranium from the inside, and the stripping agent used is dilute nitric acid.
"Wow, wow!"
After the container was opened and a large amount of dilute nitric acid was poured into the reaction tank, the reaction proceeded rapidly, and the uranium element continuously left the tributyl phosphate solvent and entered the dilute nitric acid.
After a while, the uranium element was transferred, the organic phase tributyl phosphate solvent was cleaned away, and the rest was the aqueous phase uranium-containing nitric acid solution.
But this is not over.
Immediately afterwards, Richard added the last substance, magnesium oxide, to the reaction cell.
Magnesium oxide (MgO) is an oxide of magnesium that 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. Richard carefully stored the powdered magnesium oxide in a dry barrel-shaped glass container.
At this time, Richard took the magnesium oxide powder in a glass container from the warehouse, quickly opened the container lid, and added it to the reaction tank.
Magnesium oxide enters the liquid and reacts quickly with the nitric acid contained in it. The uranium contained in it is also affected.
It is visible to the naked eye that as time passes, precipitation begins to emerge.
If you look at it seriously, it is a golden precipitation, like gold.
The glittering gold and sparkling crystals seemed to exude a dazzling luster, with a precious breath.
Its composition is magnesium diuranate, and another alias is called...yellow cake.
Yellow cake!
Yes, yellow cake!
The second step of uranium element purification is completed!
...
After the completion of the second step, Richard did not stop and carried out a lot of tedious finishing work.
After a few hours, the finishing touches were completely over, and all the sediments in the reaction tank were taken out and successfully passed the test. All this was considered to come to an end.
The final result is that a special metal bucket contains almost half a barrel of yellow cake-this is the second step of the uranium element purified product-and in order to get this half barrel of product, there are almost five hundred full The barrels of mineral powder are successively put into the reaction tank.
In other words, the ratio of raw materials to final products is almost 1000:1.
Considering other substances added in the process, this figure is even more exaggerated.
The difficulty of preparing the yellow cake can be seen from this.
But in any case, it was successfully prepared.
...
"call--"
In the protective clothing, Li Cha breathed out slowly. Through the protective gloves, the yellow cake in the metal bucket was touched by hand, and the eyes were a little shiny. He knew very well that the successful preparation of the yellow cake has greatly improved his nuclear weapons research and manufacturing plan.
After all, this is a yellow cake.
This is a real product of the nuclear industry.
Only when you get this can you be regarded as starting in the nuclear field.
Conversely, getting this is already a successful start in the nuclear field.
If you continue to develop, you will get the right to speak step by step to influence the whole world~EbookFREE.me~ This is a qualification and a threat.
Therefore, on the earth, the circulation of the yellow cake is closely monitored by the major powers. In some movies, the yellow cake is also often a key item for terrorist organizations to fight for.
Richard pouted her lips.
For him, the most important significance of the preparation of the yellow cake is that it can be regarded as a sign of success in a small period.
At this time, after testing, he has determined the uranium content in the yellow cake, which is about 60%.
This value is low, under normal circumstances, the normal yellow cake uranium content is 75%.
However, considering that there are a lot of inevitable mistakes in the first experiment, this value is acceptable, and as the experiment process is repeated and fine-tuned, the value will gradually increase and eventually reach the ideal 75%.
By then, the next third and fourth steps can be carried out.
The road is still very long, but at this time he is confident to come to the end.
He is looking forward to that day.
"Looking forward..." Richard 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 food for feeding the devil in the abyss. As he continued to prepare, as he continued to feed, eventually a terrifying great demon will crawl out of the abyss, roaring to the sky and destroying the world.
Of course, he believes that, no matter what, the chain on the neck of this terrifying demon is firmly in his hands.
Because this horror devil created it a little bit.
In a sense, this horror demon is actually himself, the animal nature he has been hiding in his body.
At that time, whether this big devil is used to destroy or create is entirely his choice.
And now he hopes that by then the situation will not be too bad, and that the world will retain a good point for him.
