Removal of Microplastics via Tannic acid-mediated Coagulation and In Vitro/Vivo Impact Assessment |
| 초록 |
Microplastics are distributed in oceans worldwide, and the negative effects of microplastics on the environment and human. Although Fe- or Al-salts are generally used for coagulation via electrostatic interactions, their microplastic removal efficiency is less than 40 %. 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 0.5 µm polystyrene beads as model microplastics, a removal efficiency of more than 90 % within 5 min was achieved. Rat intestine IEC18 cells and ICR mice exposed to microbead 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. But inflammatory factors were increased with the microplastic concentration. |
