▎ 摘　　要

NOVELTY - A formaldehyde filter material is obtained by immersing a porous ceramic plate in formaldehyde decomposition liquid comprising 1-5 wt.% graphene, 1-10 wt.% lysine, 1-15 wt.% catalase, 1-5 wt.% chitin, 5-20 wt.% aminoacrylic resin emulsion, 5-10 wt.% semicarbazide, 1-8 wt.% polyvinylpyrrolidone, 0.1-3 wt.% magnesium aluminum silicate, 1-7 wt.% negative ion powder, 1-10 wt.% propylene glycol and 20-85 wt.% water, and drying. USE - Formaldehyde filter material for air purifier. ADVANTAGE - The filter material efficiently absorbs formaldehyde from the air, and converts into a stable non-toxic compound. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of formaldehyde filter material.
