Owing to the potential toxicological threat to the environment and human health associated with microplastics, researchers have increasingly focused on microplastic removal in waste water treatment. Inspired by natural processes, metal phenolic coordination bonds have been applied to microplastic coagulation using surface phenolic-modified beads. The scope of candidate materials for cationic polymer and phenolic molecules involved in the coagulation process was expanded for surface modification, yielding a high removal efficiency(>90%) of polystyrene beads. To reduce the complexity of the two materials handling approaches, a single coagulant-phenol-modified cationic polymer was synthesized, and the removal efficiency of the beads exceeded 80% for all polymer types tested. Oxidative stress and inflammatory responses in cells treated with the purified microplastic solution were reduced to levels similar to those observed without exposure to the bead solution.
