Abstract
The present disclosure relates to a Prussian blue-based coagulant and a microplastic coagulation method using the same, which may effectively coagulate microplastics having a size of less than 20 μm or nanoplastics and implement an environmentally harmless coagulation process, and the Prussian blue-based coagulant according to the present disclosure refers to Prussian blue being used as a coagulant for microplastics present in a water-system environment.
Claims4
A microplastic coagulation method comprising:
- placing a Prussian blue-based coagulant in a water-system environment with microplastics present in the water-system environment;
- and
- coagulating the microplastics by using the Prussian blue-based coagulant under visible-light irradiation,
- wherein the Prussian blue-based coagulant comprises Prussian blue or a Prussian blue analogue.
