Adsorption is an effective way to remove microplastics from water by adhering them to an easily removable/retrievable surface. Researchers at RMIT University in Australia developed a nanopillar-stabilized metal-organic framework adsorbent that effectively removes microplastics from water, as well as the toxic pollutant methylene blue.
