The invention discloses a preparation method and application of V 2 O 5 /coal tar-based composite spherical activated carbon. , 20-40ml of absolute ethanol and 50-200ml of deionized water are mixed, magnetically stirred in a water bath and heated to 80-100°C, condensed and refluxed until the vanadium pentoxide solid is completely dissolved, cooled to room temperature to obtain vanadium pentoxide solution; the vanadium pentoxide solution was loaded on the surface of coal tar-based spherical activated carbon by immersion method, and the loaded coal tar-based spherical activated carbon was placed in a tube furnace, and the temperature was raised from room temperature to 200-500 ℃ under air conditions , for 1-4 hours, and then at a constant temperature of 200-500 ℃ for 1-4 hours; take it out after natural cooling. |
