A New Way to Clean Up Pollution

Scientists have created a new tool to help clean up dirty water. They made special foam with tiny bits of graphene and a mix of nickel and cobalt. This foam can help break down a harmful chemical called 2, 3-dichlorophenol.

How It Works

The foam is put into a tube, and water flows through it. The foam uses light to help clean the water.

Making the Foam

The foam is made by mixing graphene with a special kind of plastic. Then, they heat it up to make it strong. After that, they add the nickel and cobalt mix. This makes the foam able to clean the water.

Optimal Performance

The foam works best when it has just the right amount of graphene. Too much or too little, and it doesn't work as well. The scientists found that the best foam had a specific energy level of 2.85 eV.

Testing the Foam

They tested the foam by flowing dirty water through it. The foam cleaned the water quickly, with a rate of 0.064 per minute. Even after using it four times, the foam still worked well.

Cost and Energy

The scientists also looked at how much energy and money it takes to use the foam. They found it uses a lot of energy and costs about $329.52. But it's a good start for cleaning up pollution.
