Mineralization of polystyrene nanoplastics in water by photo-Fenton oxidation

Nanoplastics mineralization by the intensified photo-Fenton process

AI summary · Read the abstract

Researchers tested whether an intensified photo-Fenton oxidation process could break down polystyrene nanoplastics in water, finding that while complete mineralization was not achieved in six hours, the process significantly degraded the particles at elevated temperature and acidic conditions. The study contributes to developing chemical treatment methods for removing persistent nanoplastics from contaminated water.
