Beibei roams the magical starry world

Robot Xiao Cong saw Xiao Bai's anxious look, smiled and said, "Don't be impatient."

After saying that, another deep-sea camera went deep below the sea surface. At this time, the deep-sea camera was dangling around the gray liquid spit out by the plankton.

The deep-sea camera was quickly recovered and put away after nuclear contamination treatment and testing. Then the gray liquid brought back by the deep-sea camera was tested.

Soon, the robot Xiao Cong smiled at everyone and said: "There is a plan, but before I talk about the plan, I will first explain to you my discovery and purification plan ideas."

Xiaobai glared at Xiaocong and listened patiently.

Robot Xiao Cong said: "First of all, I found radioactive substances such as tritium, strontium, cobalt, uranium, plutonium, cesium, iodine, etc. in the sea. Let me talk about the uses of these substances:

Tritium is mainly used in nuclear power generation, tritium nuclear fuel cycle, and medical tracers.

Strontium is mainly used in the manufacture of strontium ferromagnetic materials, fluorescent materials, and medical treatment.

Cobalt is mainly used in high-temperature alloys and cemented carbide, manufacturing cobalt-based high-temperature superconducting materials, and medical treatment.

Uranium is mainly used in nuclear power generation, nuclear weapons, radiation detectors, and medical radioactivity.

Plutonium is mainly used as nuclear fuel, nuclear power generation and nuclear weapons.

Cesium is mainly used in medical treatment, electric vacuum devices, and optoelectronic devices.

The main uses of iodine are to treat thyroid diseases; photosensitive materials; disinfection and sterilization."

The robot Xiao Cong looked at his friends and found that they all had wide eyes, full of confusion, ignorance about themselves, and expressions of despair and hopelessness.

In order to comfort everyone, the robot Xiao Cong said: "It doesn't matter if you don't understand, as long as you know that these substances are very useful."

After listening to it, my friends suddenly came back to life. It turns out that no one understands it, so it doesn't matter if I don't understand it. Their confidence has returned.

"There are so many good things, why do they still discharge them into the sea?" Xiao Qing asked curiously

"Because the cost of refining these substances is huge, far higher than the value of these substances." Robot Xiao Cong replied

"Then what's the use of telling us this?" Xiaobai asked

"We can refine it!" said the robot Xiao Cong

"Are our refining costs very low?" Beibei suddenly became interested and asked curiously

"Beibei has the same virtue as Daddy Parrot. His eyes light up when he hears it is profitable." Jack slandered.

"No, the cost is also very high." Robot Xiao Cong replied

After hearing this, Beibei's excitement was like a ball deflating.

"However, I discovered a new substance. It is generally believed that after biodegradation, it will break down into smaller and simpler molecules, such as carbon dioxide, water, inorganic salts, etc. This view is correct.

But it is ignored that the material produced by the mutation and degradation of plankton is a new material that has not been seen on this planet before, and my database happens to have this information. These new materials will be important coating agents for our future starships. "The robot Xiao Cong said

"What's the use?" Beibei asked curiously

"What is the speed of the fastest human drone now?" asked the robot Xiao Cong.

"The X-43A unmanned aircraft has a top speed of Mach 9.6 (approximately .4 kilometers per hour)." Beibei replied.

"What's preventing humans from building faster aircraft?" the robot Xiao Cong asked.

"It should be the material. Current materials cannot withstand ultra-high speeds." Xiaohui said.

"Yes, Einstein mentioned in the special theory of relativity that when the speed of an object approaches the speed of light, its mass will become larger and larger, and when the speed reaches the speed of light, the mass will become infinite. In order to make the speed of the object To reach the speed of light, infinite energy needs to be invested. In other words, as the speed increases, the resistance encountered by the object will increase exponentially. Even if a powerful enough engine can be built, it cannot overcome this huge resistance." Robot Xiao Cong said.

"However, the coating agent we have now discovered is resistant to high pressure, high temperature, high corrosion, high spatial turbulence, etc., and has the magical function of turning ordinary materials into high value-added materials." Xiao Cong, the robot, said.

"Then we are going to make a fortune. How to operate it? Dear Xiao Cong, please tell me." Beibei jumped up excitedly, bouncing like a table tennis ball unwilling to be ordinary.

"Can we purify and refine?" Xiaohui asked incredulously

"Others can't, but we can." Robot Xiao Cong paused.

"Speak quickly!" Beibei urged.

"There is me!" said the robot Xiao Cong

"What are you going to do?" Beibei asked

"Human nature is greedy, ignorant and lucky. They will continue to dump sewage into this sea area, and I will build a purification area in this sea area to extract the elements we need. Some radioactive materials are degraded by sea plankton. , we then extract the coating agent from the degradation products." said the robot Xiao Cong.

"What kind of device is this? Can we make it?" Beibei asked worriedly.

"I can make this device very quickly. The specific working principle involves knowledge of physics and chemistry." Xiao Cong, the robot, said.

"Can you tell me how it works?" Jack asked curiously.

"The working principle of nuclear sewage extraction equipment is divided into six steps: the first step is pretreatment; the second step is multiple extraction; the third step is stripping; the fourth step is electrodeposition; the fifth step is ion exchange; and the sixth step is concentration and purification." Robot Xiao Cong said

"Can you be more specific?" Jack was not willing to only understand some superficial knowledge, and wanted to learn more about the process of refining nuclear sewage.

"If you want to know, I can explain it in depth. It doesn't matter if you don't understand. I have an impression." Xiao Cong, the robot, said.

Beibei and his friends nodded, thinking: "If you don't understand, you are a normal person, but if you understand, you are a freak." Continue to listen to Xiao Cong's explanation.

“The extraction of radioactive elements such as tritium, strontium, cobalt, uranium, plutonium, cesium, and iodine from nuclear sewage requires a series of chemical and physical processes. The specific processing flow is as follows:

The first step is pretreatment: filtration, sedimentation, acid-base adjustment, etc., to remove suspended solids and large particulate matter in sewage, and adjust the pH of the solution.

Step 2: Multiple extraction: Use organic phases such as tributyl phosphate or amide to perform multiple extractions of radioactive elements in the sewage, and separate the organic phase and aqueous phase from the water.

Step 3: Back-extraction: Transfer the organic phase containing radioactive elements from the organic phase to the aqueous phase through back-extraction.

Step 4: Electrodeposition: Electrolyze the stripped aqueous phase. Electrolysis deposits radioactive elements on the cathode one by one.

Step 5: Ion exchange: Radioactive elements that remain in the water after electrolysis are adsorbed using ion exchange resin.

Step 6: Concentration and purification: Concentrate and purify the radioactive elements deposited on the cathode through burning, dissolution, and reprecipitation.

"What are the aqueous phase and the organic phase?" Beibei asked

"The aqueous phase refers to the liquid phase composed of water and other polar solvents. The organic phase refers to the liquid phase composed of carbon-containing compounds." Xiao Cong, the robot, explained

"What is a cathode?" Xiaobai asked

"The cathode refers to the negative electrode in a battery or electrolytic cell." Robot Xiao Cong explained

"What is ion exchange resin?" Jack asked

"Ion exchange resin is a polymer compound with ion exchange function. Its function is to remove ions in water to achieve the purpose of purifying water quality." Xiao Cong, the robot, explained

The friends looked at each other and found that everyone seemed to understand, and thought to themselves: "It seems that we are all normal people, there are no freaks!"
