A method of removing a contaminant from liquid is provided. The method includes adding magnetic biological particles to a liquid containing a contaminant, sorbing the contaminant to the magnetic biological particles, and separating the sorbed contaminant from the liquid by applying a magnetic field to the magnetic biological particles. In some versions, the magnetic biological particles are pollen grains having added magnetic material. Also provided are methods of making magnetic biological particles, and compositions containing magnetic biological particles. |
