Removal of microplastics <i>via</i> tannic acid-mediated coagulation and <i>in vitro</i> impact assessment

Abstract

. 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 IEC18 cells 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.
