Abstract
A lotus leaf derived biochar loaded with ZIF-67, and a preparation method therefor and an application method thereof are provided, which relate to the field of environmental protection wastewater treatment technologies. The preparation method includes: adding a pretreated lotus leaf carrier and ZIF-67 to methanol as solvent, to obtain a solution, performing an ultrasonic dispersion process on the solution, standing the solution after performing the ultrasonic dispersion process to perform a self-assembly reaction to thus obtain a reacted solution, and drying the reacted solution to obtain the lotus leaf derived biochar loaded with the ZIF-67. Recyclability and reusability of the ZIF-67 are effectively improved by the lotus leaf derived biochar loaded with ZIF-67, and organic pollutants in aqueous solution are degraded by effectively activating peroxymonosulfate.
