Researchers in South Korea have developed a new water purification system that can filter small pieces of plastic and other contaminants very quickly and with high efficiency.
This tiny microplastic can be found almost anywhere in the world, even in places thought to be untouched: from the deepest ocean basins to the highest mountain peaks. It also ends up drinking water seamlessly as it is difficult to filter.
The key material for the new filter is a covalent triazene structure (CTF). It is a highly porous material with a large surface area, with enough space to store the molecules it captures. Such materials have recently been shown to be effective in removing organic dyes from industrial wastewater.
The resulting filter has proven effective at removing microplastics from water very quickly, and reportedly more than 99.9% of contaminants were removed within 10 seconds. In addition, the material can be used repeatedly without reducing efficiency.
