Modified carbon nanotubes and okra extract remove polystyrene microplastics from water

Scientists developed a method using modified carbon nanotubes and okra extract to remove polystyrene microplastics from water. The technique achieved over 80% removal efficiency. The process combines amine-functionalized multi-walled carbon nanotubes with okra extract as a natural coagulant aid. Optimal conditions were identified for microplastic concentration, pH, and nanomaterial dose. This hybrid system offers a potentially eco-friendly approach to microplastic removal, though further testing in real water conditions and assessment of nanotube residue are needed.
