Descripción
Microplastic fibers (MFs) from synthetic garments pose a growing environmentalchallenge, as their release during domestic laundry cycles and persistence in wastewaterhave facilitated their dispersion in aquatic ecosystems, as well as their accumulation alongthe food chain. In this context, advanced oxidation processes (AOPs), capable of breakingdown refractory organic pollutants, emerge as a promising alternative to mitigate this issue.In this study, the effectiveness of photo-Fenton to remove PET MFs was evaluated byquantifying their weight loss. Physical and chemical changes in the fibers were followedusing scanning electron microscopy coupled to energy-dispersive X-ray spectroscopy(SEM-EDS) and Fourier transform infrared spectroscopy (ATR-FTIR). Total organiccarbon (TOC) of the effluents obtained after the photo-Fenton treatment was also measuredto determine the degree of mineralization achieved. Moreover, the effect of hydrogenperoxide concentration and reaction time was investigated. A starting H2O2 concentrationof 500 mg L-1 was identified as optimal, yielding 40.6% mass loss of PET MFs after 4 h.Under these conditions, 16 h tests resulted in 99% mass loss, with high mineralizationyields (TOC < 0.5 mg L-1) . The degradation was successfully described by a cylindricalShrinking Core Model (R2 > 0.99). Progressive cavity and hole formation, and theappearance of oxygenated functionalities, were also observed upon treatment. Finally, thedegradation of MFs fragments was examined to evaluate the role of morphology, and theeffect of real fibers obtained from a washing cycle was also assessed.
