Purification System to Filter Out Microplastics
Recently, Scientists from South Korea have developed a new water purification system that can quickly and efficiently filter out microplastics. In an experiment, over 99.9% of contaminants were taken out of the water in just 10 seconds.
The polymer used is relatively inexpensive with excellent adsorption performance and good photothermal properties.
Microplastics are defined as plastics less than five millimeters in diameter—smaller in diameter than the standard pearl used in jewelry. It can be harmful to our ocean and aquatic life.
