Surface Oxidation and Defect Formation Under Five Photoaging Regimes Enhance Cd2+ and Pb2+ Adsorption by Polyethylene and Polyvinyl Chloride Microplastics

Photoaging alters polymer surface chemistry and can thereby regulate the interfacial binding of metal ions by microplastics. In this study, polyethylene (PE) and polyvinyl chloride (PVC) microplastics were exposed for three weeks to five regimes comprising UV-air, UV-ultrapure wa...
