In this presentation, microplastic coagulation using metal-phenolic coordinate bonds was used to improve microplastic removal efficiency. Plant-derived tannic acid contributed to interfacial bridging between the microplastics and Fe3+. Using 0.5 μm polystyrene beads as model microplastics, a removal efficiency of more than 90 % within 5 min was achieved. Since microplastics mostly accumulate in the gut of animals, rat intestine cells and tissues exposed to purified water from the microbead suspension were risk assessed, revealing that water purified using the coagulation-based method reduced oxidative stress and inflammatory cytokines to levels similar to those in cells exposed to water without microbeads. |
