▎ 摘　　要

NOVELTY - Water purifying and absorbing material is claimed. The absorbing material is prepared by multi-step reactions using matrix material, N-vinylamide monomer, and functional compound having epoxy as raw materials. USE - The adsorption material is useful for removing trace pollutants and heavy metals in drinking water; and detecting trace pollutants and heavy metals; and extracting compounds of different polarities and components of traditional Chinese medicine. ADVANTAGE - The adsorption material: has broad-spectrum adsorption function; removes trace organic and inorganic pollutants and heavy metals in drinking water; improves the quality and safety of drinking water; improves the hydrophilicity of the polypropylene film; and improves the water permeability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the absorbing material, comprising (i) grafting or copolymerizing N-vinyl amide monomers on the matrix material to obtain modified matrix material, (ii) hydrolyzing the modified matrix material to obtain matrix material having amine groups, and (iii) adding functional compounds having epoxy and reacting to couple them to matrix material.
