Chen Guang admired Zhuo Jingsi, in fact, Zhuo Jingsi also secretly observed Chen Guang in the process of realization, not to mention, the first time he started to do real yàn, Zhuo Jingsi's eyes lit up, the reason is very simple, Zhuo Jingsi has been doing it himself for more than four years, and he is extremely proficient in the operation of various instruments, but Chen Guangcai showed a different side when he first got started, his hands were really too stable and fast.

There is no technical content in the determination of the basic parameters of ammonia nitrogen and total phosphorus concentration, and in the actual operation, it is to hold a pipette and pour it continuously against the thermostatic heater and water bath.

The main work involves the addition of chemical agents such as sulfuric acid and hydrochloric acid.

It may only take 30 seconds for a fast person to drip out 10 times of sulfuric acid, but a slow person's hand is shaking all the time, and it may not be done in five minutes.

Just this small detail can open up a four-and-a-half-point gap, and magnify it to the entire actual process, and the difference is terrifying.

But this is not what Chen Guang does specially, but he is obviously just an undergraduate, but his thinking is extremely clear, at the beginning, his eyes were dark, he only knew that he poured solvent there, measured the absorbance with a spectrophotometer, and after watching Zhong Yue calculate it once, he would calculate the standard curve himself.

That's it, when she finished work on the sixth day and packed up her things in the office and prepared to go home, Chen Guang took the initiative to find her and asked her why the biochemical simulator composed of anaerobic tanks and two aerobic pools was designed like this, why there were differences in the size ratio of different pools, why the residence time, pH value and other parameters mentioned by Zhong Yue from time to time were adjusted in this way, and asked her why the pollutant removal rates of the anaerobic tank and the two aerobic tanks were 80%, 55%, and 35% respectively Zhuo Jingsi was completely stunned.

Zhuo Jingsi was stunned for a long time, and his brain, which had already been stiffened, came to his senses and looked at him quietly. "I've seen your academic results in the past few years, although you haven't failed many subjects, but almost none of them have more than 90 points, I thought you didn't like to study, so I thought I would pull you to the real yàn room to feel the atmosphere. Now I feel that you kid is really blind to your own brain. ”

She was a little annoyed as she spoke. Stretched out his white finger and put it on Chen Guang's head, "I feel sorry for you! Your brain is so sufficient, why are you reluctant to study hard?"

Chen Guang scratched his head embarrassedly, "You can't blame me, the atmosphere in our bedroom is like that, let's talk about it." At the beginning, everyone applied for this major because of what is the emerging industry of environmental protection, and it will be good for employment in the future. But most of the seniors who graduated early went to write a feasibility study or environmental impact assessment for the company, or they would have taken the civil service exam if they had a better foothold, but the other 50 percent of them changed careers! I can't be serious if I want to, I think I'm going to change careers in the future anyway. ”

Chen Guang said, Zhuo Jingsi also sighed, he didn't talk nonsense, Wujing University is already the first school in China to open an undergraduate major in environmental science, and it can barely be regarded as an academic pioneer in domestic universities, but after graduation, in addition to continuing to study for a doctorate. Less than half of the people who actually continue to work in the environmental protection industry are really less than 50%.

Zhuo Jingsi said unwillingly. "But that's someone else's situation, with your brain, a little bit of heart, it's not a problem to take the graduate exam, even if you can't stay in school after graduating with a master's degree, even if you go to a scientific research unit to be a project person. ”

Chen Guang shrugged. "I'm lazy. Recently, I've been in the real yàn room, and seeing that you are all so serious and busy, I can't help but think about something more. ”

In fact, he didn't say everything, but Zhuo Jingsi realized it and reacted coldly. Standing in front of him is a person with a net worth of almost 200 million, and it seems really unrealistic for him to become a scientific research worker.

She felt unwilling again, but she thought that she was so poor and sour now, and she was not qualified to talk about him, so she was stunned for a while before she said: "Forget it, I don't want to talk about you, seeing that you are so serious these days, I will invite you to dinner?"

"Okay!" Chen Guang agreed.

The two packed up their things for a while, went out side by side, and saw Luo Jin standing outside with a book.

It seems that he didn't expect Chen Guang to come out of it side by side with Zhuo Jingsi, and was caught off guard by this meeting.

"Luo Jin, is there anything wrong with you?" asked Zhuo Jingsi.

Luo Jin swallowed for a long time before pinching his nose and putting the book in front of Zhuo Jingsi, "Teacher Zhuo, I was looking at a case recently, and I want to ask you what you think, how to ...... this highly concentrated wastewater with excessive sulfate ions."

Before he finished speaking, Zhuo Jingsi didn't take his book, "There are some things that have to go first today, and you can come and ask me again tomorrow, I'm sorry." ”

Luo Jin didn't expect her to refuse so simply, and he was stunned before nodding helplessly, "Okay...... Well......"

The two went downstairs, and Chen Guang said hesitantly, "He wants to invite you to dinner." ”

In front of Chen Guang, Zhuo Jingsi didn't tell lies, "I know, so I blocked the conversation for him first." Luo Jin is a graduate student who has been shoehorned in, and his brain is quite stiff when he does academics, but he thinks a lot in other aspects. ”

"How?"

"Before, he tried to invite me to dinner for one reason or another, but I didn't think much about it at the time, thinking that he was really going to ask me something, but guess what I saw?"

"Can we stop selling it?"

"Candlelight dinner...... It can take my diaphragm badly. I'm too busy, isn't that a waste of my time?"

Chen Guang almost didn't laugh out loud, that buddy is also how bold he is, how prolific he is, and his feelings are that he has watched too many TV series, thinking that a woman can be moved by a candlelight dinner.

The two of them sat in the small restaurant outside the school, watching her war-like shaved rice, and they were busy finishing their meals after dinner.

Chen Guangdao: "Teacher Zhuo, you can eat slowly, why didn't I find out about your trait before, I still remember your delicate appearance when you first came to us as a counselor, we all thought you ate with your face." ”

Zhuo Jingsi's mouth was full of rice, and she whimpered: "I'm used to it, I can't slow down." ”

"Actually, I really admire you, photocatalyst, I almost collapsed just thinking of so many permutations and combinations that I can't count, I don't know how you survived, I always feel that you may work for nothing for ten years. ”

Zhuo Jingsi heard him talk about professional things, became interested, put down the dishes and chopsticks, and took a sip of water, "That's what I said, but you have to think like this, if someone can really find a suitable ratio and chelation method for dozens of photocatalyst materials such as silica, platinum, rhodium, and palladium, and then determine all the reaction parameters to make a finished product, and use this recyclable catalytic reaction material to achieve a removal rate of more than 90% of refractory phenolic pollutants, how much help would this be for human beings?"

Without waiting for Chen Guang to speak, she became excited again, "It's not just phenolic pollutants, but also lipids, and even conventional CODCR or nitrogen and phosphorus, as well as more difficult to deal with dioxins, which can be dealt with by using the strong oxidation in the photocatalytic environment." Once you figure it out, think about it, what a great achievement it is to put a photocatalyst grid in a very polluted river, and the visible light can catalyze the degradation of pollutants and turn these dangerous things into carbon dioxide and non-toxic and harmless organic matter for the benefit of future generations?"

Chen Guang was stunned, "I understand the truth, but it's too difficult." I've checked it on the Internet, and most of the people who are doing this thing in China are conceptual hype. ”

"But you can't deny that it can really be done!" Zhuo Jingsi was unconvinced, "We are a national key practice room, and the papers I wrote have been published in SCI journals more than ten times, this is not hype!

"Okay, okay, you're right, learning, learning. Chen Guang didn't plan to fight with her, no matter how good the prospect was for her, it was really too difficult.

Strictly speaking, just the ratio of dozens of materials, and then the coordination and chelation ratio of precious metals, it is necessary to find the optimal reaction concentration, and the possibilities in this are simply an infinite number.

What's even more terrifying is that maybe after you find the seemingly perfect ratio through the guò elimination method, change the lighting conditions, and your perfect ratio will be completely exploded again.

It's a bottomless pit!

Chen Guang looked at the familiar figure flashing by the window outside the shop, and thought in his heart.

Although she does not recognize Zhuo Jingsi's philosophy, she is indeed worthy of admiration.

"Maybe I really have to spend my whole life trapped in this thing, but I have no regrets, even if I help others do elimination, at least I have become a brick in the edifice of science, you say?"

Chen Guang sent Zhuo Jingsi to the gate of the community, and Zhuo Jingsi said this when the two separated.

Chen Guang nodded, "If you really fall into it for the rest of your life, I don't see that you have any plans to find someone to get married and live, you are so poor that you can't open the pot, I will support you." ”

"you!"

"I'm counting on you to do it, I think it's quite profitable. If you can get results, you can make a unique thing and sell it, the cost is tens of thousands of yuan, and the complete set of equipment can be sold for tens of millions of yuan, as long as the effect is good, there will be customers! I will raise you even if it is my investment!"

"Dream on you! I'm in Teacher Shu's real room, and the results I make are all in the real room, how can I sell them for you for money. ”

Not long after parting with Zhuo Jingsi, Chen Guang stopped Luo Jin.

"I knew you were going to come to me, so I could just say whatever I wanted. Chen Guang clipped his hands, looked at this angry bull-like senior with a nonchalant face, and thought to himself, this is really a poor guy.

"You stay away from Teacher Zhuo!"

Luo Jin opened his mouth and said.

Chen Guang almost didn't laugh out loud, he didn't have much to do with Luo Jin these days, although he felt that his hostility had always been there, but he was also able to accept it in the real room.

Today, I had dinner with Zhuo Jingsi, this guy couldn't hold back a little, I thought he had some realm, but why did you open your mouth so recklessly?

Remembering that he actually invited Zhuo Jingsi to a candlelight dinner, Chen Guang vaguely felt that this Luo Jin's neural circuit should not be a straight line, right? )
