The Researchers Found That The Blue Dye In The Waste Water Could Provide Energy For The Battery.

According to foreign media theVerge,

There are many theories about lithium and cobalt, but some chemists believe that future batteries can be powered by a common dye.

This fuel is methylene blue, which has a strong sapphire color.

Although the fuel looks beautiful, it becomes a harmful substance when it is infiltrated from the textile mill to the waste water.

Anjula Kosswattaarachchi, a Ph.D. candidate at the University of buffalo, has worked in textile related work at the Institute of nanotechnology in Sri Lanka, so she is very familiar with the problem of methylene blue pollution.

During the University of buffalo, Kosswattaarachchi studied a liquid battery called a "mobile battery". In addition, she participated in a project devoted to removing harmful substances from waste water.

At that time, she came up with an idea of combining the two concepts, and since then has been working on whether Ya Jiaji blue wastewater can provide energy for these liquid batteries.

At present, the research is still in its early stage, and the research team has not studied the real waste water, but it may become a way of killing two birds with one stone.

In this regard, theVerge talked to Kosswattaarachchi about why methylene blue is a problem and how it can become a battery solution.

The following is the main content of theVerge finishing:

Q: tell me about methylene blue. Is it common? Is it poisonous? Why should we use it if it is poisonous?

A: we use it because it produces a specific color.

It is the most commonly used.

One of.

It can even be used as a drug at appropriate doses.

But this dose is hard to get, and in this case it becomes poisonous.

It can lead to diseases including cancer and genetic mutations.

It also causes damage to the environment, because dyes are easy to see even at very low concentrations.

So when it is added, the penetration of sunlight will be blocked, which will damage the photosynthesis.

It may be the most studied when studying how to remove it from water.

。

Q: so your idea is to use methylene blue wastewater in the mobile battery, right? Rather than extracting dye from water, it is better to reuse water to power the battery.

A: Yes.

Q: can you explain what the mobile battery is?

A: to put it simply, there are two external containers that contain liquid electrolytes.

The electrolyte is pumped through the center and then chemically reacted to provide power for the battery.

This is a relatively new research field, but the advantage of mobile battery is safety.

They are liquids, so they do not catch fire.

Containers can be large, so you can power a lot of things on a large scale.

They can store energy for a longer time.

Q: where will methylene blue be added?

A: methylene blue is part of the liquid that we will store and pump into the container.

Usually, you have to add salt to the solution to produce chemical reactions.

Methylene blue already contains salt in waste water.

Q: so what did you find in the experiment?

A: in our experiments, we made small batteries that added methylene dyes into brine.

One charge can be used 50 times.

In addition, it is quite stable.

We calculated that when methylene blue was used as a component of the battery, we could generate 9 thousand and 600 coke per liter.

In fact, methylene must be combined with another material, so we are still studying this.

。

In addition, we still need to use real wastewater samples for testing.

This is the next thing to do.
