The new water filter can effectively Remove Smaller than Phyluoroalkyl molecules and polyfluoroalkyl, which represents a great leap forward in the fight against these “chemicals forever”.
It is difficult to remove from PFAS, a group of thousands of human chemicals that are made by the environment, but scientists were looking for new ways to solve this problem. For example, the Illinois University team found a way to remove the full spectrum of PFAs from water in one process.
However, most water filters have been developed to eliminate PFAS struggle with smaller particles. To solve this problem, a research team from the University of Monash in Melbourne designed the average bida cyclodixterin membrane with nano channels that selectively maintain PFAS while allowing water to pass. The university summarized its results in an article on Phys.orgThe saying of the device greatly outperformed the traditional polyamide membranes, which usually remove only about 35 % of PFAs short chain.
The first author in the study said: “It is difficult to manage PFAs because it dissolves easily in water and can spread away from its original source, which makes pollution difficult to contain it.” “The removal of small PFAs from water was a big obstacle on the existing filters.”
The researchers estimated that more than 20 % of Americans may be exposed to PFAs. In Australia, where the research team was based, most people have Levels that can be discovered from PFAS in their bloodAccording to the government PFAS TASKFORCE. the Agency for toxic substances and a disease record It has reached the same conclusion of the Americans.
These chemicals have been linked to a number of negativity Health resultsIncluding the increased risk of certain types of cancer, developmental delay in children, and a decrease in the ability of the immune system to do its work, according to the American Environmental Protection Agency. In addition, one study found that exposure to these chemicals can change the expressions of certain genes inside the brain, and to connect another paper raised by increasing the risk of cardiovascular disease in women after menopause.
It is not clear when the new PFAS rewriting technology may be applied in the real world, but researcher Sally El Miragawi said that the team’s approach can help pave the way for future membranes technologies designed to remove the targeted pollutants from drinking and exported water.
“He also maintains the main nutrients in water, making it an attractive way to use along with traditional nanoparticles.”
