Role of Fluorocarbon Chain Length in the Adsorption of Perfluoroalkyl Substances on Nanoplastic Particles
Science
20 Oct 2024 | ACS ES&T Water
In aquatic environments, nanoplastics and PFAS can interact through electrostatic forces, with PFAS adsorption on oppositely charged nanoplastics leading to changes in particle stability depending on PFAS chain length and water chemistry, influencing how these contaminants might spread in different water conditions.
