Abstract

The present invention relates to a nicotine-filtering medium for cigarette, using hydrated silicon oxide as carrier and containing palladium salt, and is characterized by that it contains phosphomolybdic acid or phosphotungstic acid or their soluble salt and cupric salt or nickel salt or molysite, and the weight percentages of all ingredients are 90-95, 1-5, 0.05-1 and 1-5 in turn, in which ClO2 can also be added, its weight percentage is 0.05-1. The invented composite can continuously and instantaneusly convert CO into ClO2 within 3 sec., instantaneusly restore oxidation state of conversion agent, and can effectively reduce aerosol containing several toxic materials of tar and nicotine, etc..

Description

A kind of nicotine-filtering medium for cigarette
The present invention relates to a kind of composition that transforms carbon monoxide, tar, nicotine, acetone and the ammonia etc. of removing the smoking generation.
Contain more than 40 kind of carcinogen and over one hundred kind of harmful compound in the smog (being commonly called as aerosol) that smoking produces, wherein contained acetone, ammonia, arsenic, carbon monoxide, DDT, naphthalene, hydrogen cyanide, tar, nicotine are to human body harm maximum, particularly nicotine has severe toxicity, when low dose of nervous system is played excited effect, can benumb neural when heavy dose of.Existing CO is converted into CO 2Technology in, generally adopt silica gel to make carrier, be transforming agent with the palladium bichloride, make the CO oxidation become CO 2, the latter is an innocuous substance, makes palladium recover the state of oxidation of its positive divalence by airborne oxygen by cupric again.The shortcoming of this technology is only can remove CO, and is powerless to removing above-mentioned multiple poisonous substances such as nicotine and tar, and this technology is converted into CO with CO 2Need second more than 80, speed is slower, and the regeneration rate of its transforming agent is also undesirable.
The purpose of this invention is to provide a kind of nicotine-filtering medium for cigarette, it can remedy the above-mentioned deficiency of prior art.
Nicotine-filtering medium for cigarette of the present invention is carrier with the hydrated SiO 2, and contain palladium salt, it is characterized in that wherein also containing phosphomolybdic acid or phosphotungstic acid or their soluble-salt, cupric salt or nickel salt or molysite, the percetage by weight of each component is followed successively by 90-95,1-5,0.05-1.0 and 1-5.
Composition of the present invention can constantly can be converted into CO with CO in the moment less than 3 seconds 2, and moment recover the state of oxidation of transforming agent, can reduce the aerosol of multiple poisonous substances such as containing tar, nicotine effectively.
Below by embodiment the present invention is described.
Embodiment 1
Get 920 gram hydrated silica gels, soak with 1 gram phosphomolybdic acid, add the aqueous hydrochloric acid solution that contains 40 gram palladium bichlorides and contain 39 gram copper chlorides more respectively, mix, anhydrated 2 hours 60～70 ℃ of following dryings, wore out 4 hours in atmosphere then, be nicotine-filtering medium for cigarette of the present invention, it is a kind of solid shape composition of yellow.This composition 0.1 gram is put into cigaratte filter, less than 80% of the CO that produces being converted into CO 3 seconds 2, and can the moment occlusion contain aerocolloidal 90% of multiple harmful substances such as tar, nicotine.
Phosphomolybdic acid can for example sodium phosphomolybdate or phosphotungstic acid potassium be replaced with the phosphotungstic acid of same quantity or their soluble-salt in the present embodiment.Palladium salt in the present embodiment can adopt palladium bichloride or palladium sulfate, and cupric salt can be used divalent nickel salt or divalent iron salt instead.As hydrated silica dehydration in dry run of carrier, absorbed moisture content again owing to deliquescence from air before using in ageing process in the present embodiment, its water content can reach 40%, and it can strengthen CO better and be converted into CO 2Speed, and help containing the aerocolloidal absorption of poisonous substances such as tar and nicotine.Except hydrated silica, can also adopt cellulose family, aluminium oxide, polyethylene glycol, water imbibition resin, foamed plastics etc. to make carrier.This nicotine-filtering medium is yellow, and CO is being converted into CO 2Moment become blueness, become brownly, dark brown subsequently again, this is because due to the compound chemical valence of palladium salt and phosphomolybdic acid changes, and along with absorption, the conversion amount of poisons increase color burn.
Embodiment 2
Identical with embodiment 1, just in making this nicotine-filtering medium process, except above-mentioned batching, also add a spot of ClO 2, its percetage by weight is 0.05～1.Add in the present embodiment and contain 5%ClO 2Aqueous solution 20g, but in heating process used ClO 2Partly, hydrochloric acid all vapors away adding ClO 2Can make the nicotine-filtering medium of making in use quicken the process of change color significantly, illustrate catalytic action is played in the conversion of CO.
Nicotine-filtering medium for cigarette of the present invention also can be used for purifying air, and it can make airborne CO, O 3, toxic gas such as ammonia, hydrogen sulfide is converted into innocuous substance, be placed in the air-conditioner for this it or the gas defence cover in get final product.

Claims (2)

1. nicotine-filtering medium for cigarette, be carrier with the hydrated silica and contain palladium salt, it is characterized in that containing phosphomolybdic acid or phosphotungstic acid or their soluble-salt, cupric salt or nickel salt or molysite, the percetage by weight of each component is respectively 90-95,1-5,0.05-1 and 1-5 successively.
2. nicotine-filtering medium for cigarette as claimed in claim 1 is characterized in that wherein having added CO 2, its percetage by weight is 0.05-1.
