New method of water filtration using carbon nanotubes Bashny.Net

Now for water filtration commonly used silicone gel and activated carbon. These materials can only be used to develop the resource, after which they must be disposed of. Recently, scientists introduced the filters with carbon nanotubes, which are more effective in removing organic pollutants, and they can be reused.





Researchers from Rochester Institute of technology under the leadership of Reginald Rogers has created a single-walled carbon nanotubes — microscopic rolled-up sheets of graphene, which, in turn, constitute a sheet of carbon atoms, one atom thick. Then, these nanotubes were sorted depending on what type they are — semiconductor or metal. The semiconductor tubes were subsequently included in the thin carbon sheets, which are then used for water filtration.





Because the nanotubes repel water molecules, it does not get stuck in the material, allowing it to adsorb more organic substances.

Once the sheets are filled with pollutants, they just need to put in the microwave for five minutes to clean off the contaminants, after which the leaves can be used again.

According to the developers, this is a brand new and very promising method of water filtration. published
