Then the removal of microplastics, extracted from face cleansing cream sample 13, is also successfully carried out in 0.2% H2O2 solution. Similar to microscale zeolites, the microplastics are also removed efficiently by the motile assembled chains under magnetic field (Figure , Video S8), and the removal efficiency is about 71% (Figure ). Those two cases elucidate that this novel magnetic assembled chains performed excellently by shovelling effect in H2O2 solution.
