Abstract

The present disclosure relates to a water treatment material for electrically enhanced adsorptive filtration, and a preparation method and use thereof. In the present disclosure, a melamine sponge is carbonized under protection of an inert gas, so that the sponge has a satisfactory electrical conductivity. Then, a N-rich melamine sponge is further prepared by amino modification and is utilized as a precursor, which has a larger specific surface area. The dopamine and the polyethyleneimine are modified to improve the adsorption potential of the sponge.
