424: C424 The Effect of the Manganese Acid

C424 The Effect of the Manganese Acid

"Professor Qin, the materials you asked for." The assistant said with a smile.0

"Thank you." Qin Luo nodded and thanked him. He took a bottle of concentrated sulfuric acid from the handcart. He poured it into the beaker, put it in the icy water bath, and slowly stirred it. A moment later, Qin Luo picked up 100 grams of graphite powder and 1 gram of sodium nitrate solids and slowly poured them into the beaker.

"Qin, did you put too much graphene powder in?" Seeing Qin Luo's actions, Lee Min's forehead slightly wrinkled, and his expression was somewhat serious.

As the director of the laboratory, he was naturally not a vase. Lee Min himself was a double professor of physics and chemistry. He had prepared graphene more than once through the oxygen restoration method. He knew the entire preparation process clearly.

However, it was his first time seeing Qin Luo pour so much graphene powder at once and only add a little sodium nitrate solids.

A ratio of 100: 1, could it cause a chemical reaction?

"Not much, I even feel that it's a little bit too little." Qin Luo smiled slightly and poured the remaining 100 grams of graphite powder into it. He then used the magnetic stick to stir the beaker.

... "" Looking at this unbelievable method of operation, Lee Min was completely speechless.

As expected, theory was theory and practice was practice. Even the person who proposed the theory might not be able to succeed.

Thinking of this, Lee Min waved his hand to his assistant again. "Go to the warehouse and get some graphite powder."

"Yes." The assistant nodded and wanted to turn around, but in the next second, he froze on the spot.

He saw Qin Luo stirring the beaker while he picked up the high manganese acid and poured it into the beaker!

At this moment, everyone, including Lee Min, widened their eyes!

Before everyone could recover from their shock, the beaker had already started boiling. Bubbles began to appear continuously, and at this moment, everyone's hearts also began to boil.

They knew that the most critical moment had arrived. If Qin Luo could keep the temperature of the reaction at 90-98 degrees and maintain it, then he would be able to prepare graphene!

But how to maintain the temperature became the first problem that needed to be solved.

"What will he do?" Lee Min narrowed his eyes and stared at Qin Luo, or rather, at his hands.

He really wanted to see what kind of materials Qin Luo would add.

It was only a matter of time. When the reaction was about five minutes, Qin Luo, who had been waiting for a long time, finally moved. He took down the H2O2 regenerative agent from the shelf.

H2O2 regenerative agent!

Lee Min's eyes were red and his body was shaking violently. Qin Luo's choice had once again exceeded his expectations!

Under everyone's astonished gazes, Qin Luo picked up the H2O2 Regenerative Oxidizer and poured it into the beaker.

The beaker boiled again. Through the thermometer at the side, at this moment, the temperature of the beaker's reaction was as high as 98 degrees!

This was the temperature of the reaction!

One minute, two minutes, ten minutes, half an hour!

When the reaction temperature had just dropped, Qin Luo picked up the tweezers and clamped the beaker with them. He used the diluted acid solution with a volume ratio of 1: 10 and washed it with ion age until there was no sulfuric acid detected in the filter.

At this moment, at the bottom of the beaker, a layer of graphene was faintly visible.

He succeeded!

He successfully produced graphene through the oxygen restoration reaction, and it looked like the quality was not bad!

Seeing this scene, Lee Min could not suppress the shock in his heart.
