Separation of Microplastic Particles from Sewage Sludge Extracts Using Magnetic Seeded Filtration

ABSTRACT: Highlights • Magnetic seeded filtration can efficiently separate microplastics from cellulose.• Enzymatic and oxidative treatments only marginally affect separation efficiencies.• Hydrophobic interactions govern the hetero-agglomeration process.• The agglomeration behavior of PVC differs from that of other microplastics. Graphical abstract Microplastic particles (MP) are efficiently retained in wastewater treatment plants and enriched in sewage sludge. For monitoring MP contents in wastewater systems, sewage sludge is thus well suited, but also requires an isolation of MP from the sludge matrix, as other sewage sludge components may interfere with the MP identification and quantification. Although organic matter in sludge samples can be removed through acid and enzymatic digestion procedu
