To treat thallium poisoning, you need to synthesize Prussian blue!

To synthesize Prussian blue, a series of chemical experiments are required and a large number of precise experimental tools are used!

The question is, what should I do without precise experimental tools?

Two words: Make do with it!

If there is no alcohol lamp, just use a burning knife instead. This is a soju brewed with sorghum. It has a high degree of degree and a strong taste. It is like a knife cutting in the mouth. The key is that it can be ignited directly!

Burning knives are a specialty in Liaodong area and are relatively rare in Henan. The Li family sent a large number of people to sweep the big and small hotels near Qi County and boiled pots, and then they found more than a dozen jars!

Xue Yu slightly modified it to make a large alcohol lamp, which barely solved the heating problem!

If there is no test tube, just use a small porcelain bottle to make do with it. It is also a fine product produced by Jingdezhen-Official Kiln during the Yongle period of the Ming Dynasty. If this were placed in later generations, it would be a precious cultural relic worth tens of millions, and it would really feel like using it!

There is no funnel, so I made do with the funnel used to make a comeback from the grocery store!

There is no crucible, so I just used it as a casserole for cooking mutton!

Conduit, beaker, evaporation dish, gas scrubber... everything you want is nothing, you can make do with other things!

After half an hour, he cleaned various tools and assembled them, Xue Yu couldn't help but curl his lips and realized a serious problem.

I was so bragging about it before. I was just such a simple tool. Not to mention 30% of the time, I am afraid that even 10% would be difficult.

But at this point, if I quit, I am afraid that Li Jingbai and his wife will either hang themselves with a rope or draw a knife to wipe their necks, and they will not be able to survive anyway.

There is nothing to do with hope. It is the most painful thing to see hope and lose hope!

Therefore, I can only bite the bullet and whether I can succeed depends entirely on God’s will!

"Everyone listen. Now you have started to configure the antidote. Be careful, take it gently, put it on the gloves, and no one is allowed to touch the items directly. This operation is extremely dangerous. If you find that the situation is wrong, you will turn your head and run away immediately. Do you understand?"

"Understood!"

"Okay, start!"

Dangers are inevitable when conducting chemical experiments. In history, many chemists died in experimental accidents, some were poisoned, some were exploded, and some were burned to death.

Nowadays, the tools and equipment are simple, and they are also an inexperienced person. With a group of people who have no experience and no knowledge of chemistry, the danger is several times, or dozens of times!

Therefore, Xue Yu repeatedly explained it many times and asked the irrelevant person to retreat ten feet away before the experiment started!

"Gudu!Gudu!"

First put a small bag of fine salt into a white porcelain basin, and then pour a bottle of green alum oil. After the two come into contact, a large amount of white foam suddenly emerges, just like a pot is boiled, and white smoke rises!

Then I used a large iron pot to cover the white porcelain basin tightly. A small hole had been chiseled at the bottom of the pot, and a long arched bamboo tube spliced ​​together was inserted. The outlet was inserted into another white porcelain basin, filled with water!

This water is not well water or river water, but rootless water, that is, rain water!

Well water, there are too many impurities in the river water, and chemical experiments cannot be conducted. Rain water is distilled water produced in nature, which is relatively pure!

In ancient times, wealthy families liked to take some rootless water during the rainy season in September and store it in a large jar for tea making. It is said that the taste is more fragrant!

There were more than a dozen tanks of rootless water stored in the cellar of the Li family, and they were filtered repeatedly with gauze dozens of times, which was barely available.

Green alum oil, the main component is sulfuric acid. After chemical reaction with salt, it produces sodium bisulfate, a white precipitate, and hydrogen chloride gas!

The hydrogen chloride gas passes through the bamboo tube and is integrated into the distilled water, which becomes dilute hydrochloric acid!

Then the hematite ground into powder was put into dilute hydrochloric acid, and the two reacted chemically, thus forming water and ferric chloride!

Looking at the red-brown solution that appeared, Xue Yu's heart was relieved by half. After the iron trichloride was successfully manufactured, Prussian blue had hope.

But, another important substance is needed: potassium ferrocyanide!

"Come here, kill the cow, and get a bucket of hot cow blood!"

"ah?"

A strong yellow plowing ox had been led by a long time ago and was tied under the big willow tree in the backyard.

A tall servant stepped forward, covered the cow's head with his torn clothes, pulled out a sharp knife, aimed it at the scalper's heart, and gestured back and forth several times, but he was reluctant to take action!

It’s not that I can’t bear to kill the cattle, but that I really don’t dare!

Huaxia is an agricultural nation and attaches great importance to agricultural production. In ancient times when productivity was backward, livestock was the most important production tool!

Therefore, strict laws have been formulated in all dynasties, prohibiting the arbitrary slaughter of large livestock such as cattle, horses, etc., and those who violate the situation will be severely punished!

For example, the laws of the Han Dynasty clearly stipulated that: "No killing cattle, those who violate the ban will be punished!"

Whoever kills the cow will have to pay the life. Even the owner of the cow is no exception. I will ask if you are afraid?

It was not until the Tang Dynasty that the rule of killing cattle and paying for life was abolished, but he had to spend a few years in prison and impose a large fine!

Therefore, the heroes of the martial arts world slapped the table and asked the waiter to give two kilograms of beef and ten kilograms of fine wine to only appear in storytelling stories or novels!

In reality, whoever dares to do this, either his butt is broken or his army is exiled to three thousand miles away!

The laws of the Ming Dynasty were known for their rigorous ox management, and they were even more strict in managing oxen. Who has a cattle, how many cattle are there, when to give birth to a calf, when to resell it, etc. all need to be registered with the government.

Those who kill someone else's ox plowing must be 200 rods and sentenced to two years in prison. Those who kill their own ox plowing must also be 100 rods and sentenced to one year in prison. If the ox dies of illness and does not report it, they will also have to be whipped forty times, and all the tendons, horns, and skins are not accepted into the official!

The Li family member did not have the courage to hold the knife, but he was reluctant to take action, so he had to look at Mr. Li not far away.

Li Jingbai is an upright person and never abolishes his public for personal gain. Now, in order to save his son's life, he has only made an exception, so he nodded fiercely!

"Brush!...moo!"

After obtaining tacit approval, the servant stabbed the sharp knife in his hand. The scalper screamed a few times, and his huge body fell to the ground, and blood gushed out of the wound... Someone came forward with a wooden barrel and took a full bucket of blood!

At the same time, Li Jingbai called the old housekeeper and whispered a few words in his ear. The latter nodded and made proper arrangements!

The Ming Dynasty law stipulates that plowing oxen is not allowed to be slaughtered privately, and violators are severely punished!

However, there is another rule: Those who commit suicide or die of illness will not sit!

It is to kill the plowing ox by accident, or the plowing ox dies of illness. Since it is unintentional and non-personnel, the owner of the livestock may not go to jail. Just report it to the government and pay some fines!

Therefore, in the families of high-ranking officials and nobles, they will always "death from illness" one or two cows during the holidays. Everyone knows it well, and no one just points it out!

Return to the book!

Xue Yu injected fresh cow blood into the crucible and added some wood ash. He then heated it with an alcohol lamp while stirring it gently with a wooden spoon.

After half an hour, after using three jars of soju, I finally burned the crucible, carefully scraped off the remaining substances inside, dissolved them in distilled water, and stirred them slowly evenly.

After it is fully saturated, pour it into a bottle covered with four layers of gauze and two layers of linen. After repeated this many times, the gauze and linen are covered with black and brown residue, and a yellow liquid appears in the bottle!

It turns out that wood ash contains potassium carbonate, bovine blood contains ferrous, and there are two elements: carbon and nitrogen. After the two are mixed and heated, they can obtain potassium ferrocyanide, which is the yellow solution, commonly known as: yellow blood salt!

Ferrochloride and potassium ferrocyanide have been made one after another, and the last step is missing to merge. Is it still unsure whether it can be successful!

Because raw materials and experimental tools are all made up, any mistake in any link may lead to failure!

"Newton, Mendeleev, Madame Curie... and the respected chemistry teacher, you must bless me!"

Xue Yu recited it silently several times, took a deep breath, and slowly merged the two solutions in proportion... A wonderful thing happened. After the red-brown solution and the yellow solution met, it instantly turned into a new dark blue substance: Prussian blue!

"Little miracle doctor, what's wrong?"

"Fortunately, I'm not humiliating my fate!"

Low-quality materials, simple tools, inexperienced operators... Thanks to God's blessing, I still succeeded by chance. The whole process was basically smooth, with only a little flaw, which hurts a person-Doctor He!

The old doctor is over 60 years old, but he is very curious and insists on joining the experiment. While watching Xue Yu's experimental steps, he secretly makes small moves, causing the hydrochloric acid to burn the hand. He still doesn't care, but looks novel!

In the spirit of Shennong tasting hundreds of herbs, whenever a new substance is synthesized, the old medical officer wants to taste it in person. If Xue Yu hadn't discovered it early and stopped it in time, he would have been killed!

The Prussian blue was made and filtered repeatedly several times. Then, a small bowl was served and placed next to Mr. Li's mouth, but he didn't dare to pour it into him for a long time!

Because using Prussian blue to treat thallium poisoning has a bit of meaning to fight poisoning. If the dose is small, it is not enough to relieve thallium poisoning, and Mr. Li will not escape death!

If the dose is large, the original toxin is eliminated and a new toxin is born again, and Mr. Li will still be unable to escape death!

There are no medical equipment, so checking the toxin content in Mr. Li’s blood. It is too dangerous to use medicine just by feeling!

"Li Xin, Mr. Li, I have tried my best. Whether you live or die in a while depends on your own luck. If you accidentally kick your legs and go to the underworld, don't complain to the King of Hell!"
