Abstract

The occurrence of microplastics (MPs, <5 mm) and nanoplastics (NPs, <1 μm) in the marine environment is raising strong concerns since they can have potentially negative effects on human health. Polyethylene terephthalate (PET) is a common polymer found in aquatic environments and the influents and effluents of wastewater treatment plants due to the growing global consumption and their resistance to degradation [1]. Heterogeneous photocatalysis (HP) is a useful treatment technology for removing nanoplastics (NPs) from water due to its high efficiency, low cost, and operation facility [2]. This study investigated the photocatalytic activity of TiO2/MIL-100(Fe) of PET NPs degradation in an aqueous solution under solar radiation.
