Descripción
In this study, kinetic models for the photo-Fenton oxidation of polystyrene nanoplastics(NPs) in water were developed, considering particles with decreasing diameters. Variousreaction parameters affecting the oxidation rate, such as particle size (140−909 nm), agitation speed (250−1000 rpm), and operating temperature (25 and 60 °C) were investigated. Oxidation progress was evaluated through turbidity measurements, TEM, and FTIR analysis, while leached intermediates were identified via Pyr-GC-MS and IC. Due to changes in NPs surface reactivity, the overall reaction rate was divided into two stages, following a freeradical mechanism. Using equations derived from the classic Shrinking Core Model, the oxidation of NPs was determined to proceed under chemical reaction control, with negligible mass transfer limitations. Additionally, the Prout-Tompkins model was found to accurately represent the degradation process. The proposed mechanisms and models provide valuable insights for describing and predicting the advanced oxidation of NPs under different operating conditions and treatment methods.
