Embodiment 1

[0034] The Fe obtained by the method described in the implementation method 2 o 3-M is granulated by an ordinary granulator, the particle size is controlled at 40-60 mesh, and added to the cigarette filter by the normal method of adding activated carbon tip rods, the amount of which is 5 mg per cigarette, and the final cigarette product is Tar can be reduced by 20%, ammonia by 30%, and benzo[a]pyrene by 20%.

Embodiment 2

[0036] The Fe(OH)-M prepared according to the method described in the implementation method is granulated by a common granulator, and the particle size is controlled at 40-60 mesh, and added to the cigarette filter by the normal method of adding activated carbon tip sticks. 5 mg per cigarette, the final cigarette product can reduce tar by 16%, ammonia by 25%, and benzo[a]pyrene by 25%.

Embodiment 3

[0038] The Fe obtained by the method described in the implementation method 2 o 3 -M and Fe(OH)-M are uniformly mixed in a ratio of 1:1, then granulated by a common granulator, the particle size is controlled at 40-60 mesh, and added to the cigarette filter by the normal method of adding activated carbon tip sticks, The addition amount is 5 mg per cigarette, and the final cigarette product can reduce tar by 18%, ammonia by 27%, and benzo[a]pyrene by 22%.

Abstract

The invention relates to a modified montmorillonite filter additive containing iron oxide or hydroxy iron and application. Montmorillonite and the iron element are combined, and hydroxy iron ions are inserted among 001 crystal plane layers of montmorillonite by way of ion exchange and are distributed in a nanoscale state. Through the scanning electron microscope, physical adsorption, ammonia chemical adsorption and cigarette addition experimental test, the results indicate that the specific surface area of pillared montmorillonite is enlarged and the capacity of adsorbing ammonia and smoke particulate matters is improved. The hydroxy iron modified montmorillonite filter additive has a certain selective adsorption effect on benzo[a]pyrene in the cigarette smoke. The filter additive has the advantages of strong plasticity, good adsorption effect, safety and no toxicity, is low in price and is applicable and efficient.

Description

Technical field [0001] The present invention involves the field of cigarette technology. Specifically, it is a modified monopoly filtering agent and application of nano -e -iron dioxide or / and hydroxylkye iron. Background technique [0002] In recent years, as the safety requirements for cigarettes have increased, how to reduce the content of harmful substances in cigarettes has become a topic of general concern for the tobacco industry and medical community; cigarette reduction reduction and coke reducing their importance have also shown their importance.The use of filter additives is a very good method of reducing hazards.Although there are more and more research on smoke adsorption materials, only activated carbon additives are really used in large -scale large -scale. [0003] Mengliten is an excellent porous modified matrix material. It has a variety of advantages such as natural distribution, cheap prices, and safety and harmlessness.The 001 crystal layer of the litter is v...
