| titleOfInvention | A kind of graphene polysaccharide modified cigarette filter that selectively intercepts benzene ring harmful substances and preparation method thereof |
| abstract | A method for preparing a graphene polysaccharide-modified cigarette filter that selectively intercepts benzene ring harmful substances, characterized in that, in the preparation method, each reagent is in parts by weight, comprising the following steps: (1) preparing graphene oxide; (2) ) reduced graphene oxide; (3) preparation of water-soluble polysaccharide; (4) preparation of reduced graphene oxide/water-soluble polysaccharide; (5) modified cellulose acetate; the cigarette filter prepared by the present invention can significantly reduce coke Harm reduction, improving the quality of cigarettes, the taste is mellow, and at the same time reducing the content of benzene ring substances 3,4-benzopyrene and phenol in the smoke to 45% to 65%, which can further reduce the harmfulness on the basis of the existing cigarette quality . |
