Microplastics are distributed in oceans worldwide, and the negative effects of microplatics on the environment and human health are increasing. Although Fe- or Al-salts are generally used for coagulation of microplastics via electrostatic interactions, their microplastic removal efficiency is less than 40%, and the smaller the size, the lower is the removal efficiency. In this study, 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 5 μm polystyrene beads as model microplastics, a removal efficiency of more than 90% within 5 min was achieved. In vitro and in vivo tsets, water purified using the coagulation-based method redcued oxidative stress and inflammatory cytokines to levels similar to those in cells exposed to water without microbeads. |
