Now that Professor Zhong has spoken, if Zhang Yi is still hiding, it will be too shameless.

Tungsten molybdenum separation is only an inconspicuous experimental project for Zhang Yi, and there are very few experts and scholars in this area in 98 years, and there are few results.

However, after entering the 21st century, there are many researchers on tungsten and molybdenum separation, and the results are becoming more and more abundant, and by 2017, before Zhang Yi crossed, tungsten and molybdenum separation technology has been very mature in industry.

Zhang Yi thought for a moment, picked a tungsten-molybdenum separation scheme with mature technology in his brain, and said calmly: "Tungsten-molybdenum separation is actually very simple, as long as you understand the huge difference in the affinity of tungsten and molybdenum ions to sulfur, you can find the right solution." ”

"Its essence is to sulfide molybdenum into MoS42- through a vulcanizing agent, while tungsten remains as WO42-, and then use the significant chemical differences between MoS42- and WO42- to achieve tungsten molybdenum separation. ”

"Is this possible? What is the vulcanizing agent?" Professor Zhong suddenly became interested at this moment, completely forgetting that Zhang Yi had been sentenced to death in his heart just now.

Since Professor Zhong wants to know, then half of his goal has been achieved, Zhang Yi continued: "It is completely possible, the vulcanizing agent can choose phosphorus pentasulfide, which has a sulfur content of up to 72%, and the hydrolysis produces HS- which can provide a sulfur source for molybdenum vulcanization, and the relatively low price of phosphorus pentasulfide will greatly reduce the cost of tungsten molybdenum separation, and as a solid sulfur-containing compound, it is more convenient to transport and store in the process of tungsten smelting." ”

Li Mowen listened to it in a fog, and he didn't know what Zhang Yi was talking about, but he could see one thing, Zhang Yi was now talking to Professor Zhong about the plan for tungsten and molybdenum separation.

This frightened him, didn't it mean that this project was difficult? Didn't it mean that no number of professors could do this project? Why was Zhang Yi able to tell the truth?

Liu Rui listened and thought, and the shock in his heart became stronger and stronger, in fact, he collected so much information, studied almost all the cases of tungsten molybdenum separation that could be collected at home and abroad, and the understanding of tungsten molybdenum separation has accumulated to a certain extent.

But I can't find such a breakthrough point, and now Zhang Yi has put forward a new idea, which suddenly made Liu Rui understand more thoroughly like an enlightenment, this is the project of his graduation thesis, at this time he has a new understanding, and it also makes him smile and smile a little more.

Xia Jingyan listened and memorized when Zhang Yi spoke, and at this time a lot of things had been written in the small book, and some words she didn't understand planned to ask Zhang Yi later.

However, the worry on her face has faded, and she is no longer worried when Zhang Yi begins to tell, Zhang Yi at this time is the same as when he was doing experiments, he is full of confidence in his conversation, and judging from the professional terms he said, it is possible that he can really make tungsten molybdenum separation experiments.

She really read it right, Zhang Yi is really amazing.

I don't know why, her face turned a little red at this time, is it because from the beginning, she had a premonition that Zhang Yi would behave like this? Or did she just care?

Professor Zhong also thought about it for a while after listening to Zhang Yi's plan, obviously he did not have a good grasp of tungsten molybdenum separation, Zhang Yi's plan is actually very feasible, but I don't know whether the effect is good or not.

"The plan you mentioned may be feasible, but you will only know how effective it is after experimental verification. The expression on Professor Zhong's face has completely relaxed, so that Zhang Yi still really understands some tungsten molybdenum separation technology, if the scheme he said has a good effect, what he said before tungsten molybdenum separation is not difficult or may be true.

"Professor Zhong, you can't listen to what he has to say, right? I haven't done any experiments, how can I say that I can solve it if it can be solved?" Seeing that Professor Zhong seemed to be immersed in thinking about Zhang Yi's plan, Li Mowen suddenly became anxious.

He is different from Zhang Yi, Zhang Yi is to die to save face and suffer the crime, if someone asked him at the beginning if he said that tungsten molybdenum separation is simple, he will definitely not admit it, a fool will admit it, and he will lose his face if he can't do it.

He didn't believe that Li Mowen was killed, but Professor Su told him before coming to the research group that he had not planned to carry out this experiment before, and it was only an exploration and exploration.

Anyway, Professor Su can't handle this project, saying that it is a relatively difficult project in the scientific research community, if Zhang Yi can do it, is Professor Su lying to him? How is this possible?

He still firmly believes that Zhang Yi is fooling, who knows if Zhang Yi is afraid of losing face and casually pulling the plan, anyway, he has never done it, who knows what the result will be.

"Li Mowen, you go back and tell Professor Su about your joining the research group, I want to talk to her. At this time, Professor Zhong suddenly spoke, his tone a little cold.

Li Mowen instigated Zhang Yi from the beginning of the meeting, and Professor Zhong was not stupid, so he could naturally see that his impression of Li Mowen was a little worse.

Even if it was really Zhang Yi's nonsense, Li Mowen said it at this time, it was inappropriate, no matter how he said it, he was a classmate of a research group, and in order to overcome this project, it would not be an exaggeration to say that he was a comrade-in-arms and a partner.

And Li Mowen obviously has no team spirit, and even sow discord, which is the most taboo thing for a team, Professor Zhong doesn't want his team to get into internal trouble before they start to get into the main topic of the project.

Later, it turned out that Zhang Yi was still very level, and he had also seriously thought about this plan, and there was a possibility that tungsten and molybdenum separation could be solved, and the results would not be known until verification and verification.

However, Li Mowen is no different from a mouse, but don't spoil a pot of porridge because of him.

"This ...... Professor Chung, I think this is a misunderstanding. Seeing Professor Zhong's serious expression, Li Mowen suddenly became scared, and his tone of voice trembled a little, he spent a lot of effort in the research group, and now he was about to be kicked out before he caught up with Xia Jingyan, how could he be willing.

In fact, he is more worried about Xia Jingyan's opinion of him, in his opinion, as long as he wins Zhang Yi, he will have no competitors, girls like the strong, if Zhang Yi is driven out of the research group, then Xia Jingyan will definitely be very disappointed in him.

But now that Professor Zhong is actually going to drive him out, won't he have to lose face? Can Xia Jingyan still look up to him? Li Mowen began to worry.

"Okay, you go back first, I'll talk to Professor Su about anything. After Professor Zhong finished speaking, he stopped paying attention to Li Mowen, and the office suddenly became quiet without any sound.

Li Mowen's face was bloodless, his two hands were clenched together, and his finger joints were white.

Professor Zhong was already determined to let him leave, and he didn't dare to look at Xia Jingyan anymore, so he stood up and walked out of the office silently with his head down.

After Li Mowen left, the atmosphere in the office was still a little dignified, after all, this time it was a little unpleasant, and the few people present were not very comfortable.

"Zhang Yi, can you take the time to do your technical solution?" Professor Zhong still cares about Zhang Yi's technology very much, if it can be successful, it will definitely be a major breakthrough in scientific research for him.

"Yes, Professor Zhong can arrange it at any time. Zhang Yi nodded and said.

"Alright, then you'll be in charge of this experiment when it's arranged. Professor Zhong directly handed over the responsibility to Zhang Yi, and he still had some confidence in Zhang Yi's plan, it didn't matter whether it was successful or not, how could he be afraid of failure in the experiment.

After the meeting ended, Zhang Yi and Xia Jingyan left the office together.

When the two walked side by side in the aisle, Zhang Yi whispered to Xia Jingyan: "Thank you, you helped me speak just now." ”

The so-called adversity sees the truth, his friendship with Xia Jingyan is actually not very deep, and it is very rare to be able to help him speak in that situation.

Xia Jingyan smiled and said: "You're welcome, in fact, it's me who should apologize, this matter is completely because of me, but it has caused you a lot of trouble." ”

"Well, let's not be too polite either. Zhang Yi also smiled when he heard this, it seems that the beautiful student bully looks really good when she laughs.
