Achieving over 98% Efficiency in Removing Nanoplastics from Water: A Breakthrough Discovery
Scientists at the University of Missouri are working to combat the harmful effects of nanoplastics on human health. Nanoplastics, which are smaller than the width of a human hair and invisible to the naked eye, have been linked to cardiovascular and respiratory diseases. These tiny plastic particles are accumulating in bodies of water around the world, posing a threat to both wildlife and humans.
In response to this growing concern, researchers at Mizzou have developed a new liquid-based solution that can remove over 98% of nanoplastics from water. This innovative method uses water-repelling solvents made from natural ingredients to absorb and eliminate the microscopic plastic particles. The researchers are also exploring ways to recycle the solvents for multiple uses.
The process involves placing the solvent on the water’s surface, allowing it to absorb the nanoplastics, and then removing the solvent with a pipette, leaving behind clean water. The researchers aim to scale up this process for application in larger bodies of water like lakes and oceans.
The new method is effective in both fresh and saltwater and is made from safe, non-toxic components. By developing effective removal methods for nanoplastics, the researchers hope to drive innovation in filtration technologies, gain insights into nanomaterial behavior, and support the development of environmental policies.
In their study, the Mizzou team tested different sizes of polystyrene-based nanoplastics and achieved better results than previous studies that focused on just one size of plastic particles. This research represents a step forward in the fight against nanoplastic pollution and its detrimental effects on ecosystems and human health.
