Different oxidation treatments on polystyrene (PS) microspheres by using an ultraviolet/ozone (UVO3) system

This study investigated the effects of oxidation of polystyrene (PS) microspheres by three different treatments namely oxidation by ozone aeration only, UV irradiation only or by the combination of both (UV/O3), by using a self fabricated UV/O3 system. Results expressed in carboxylic acid functional...
