Embodiment 1

[0019] Select phenol as the imprinting molecule, 2-vinylpyridine (2-VP) as the functional monomer, ethylene glycol dimethacrylate (EDMA) as the cross-linking agent, and azobisisobutyronitrile (AIBN) as the initiator; Weigh 0.0941g of phenol and dissolve it in 10 mL of chloroform, add 0.42 mL of 2-VP, shake at 25 °C for 3 h (150 r / min), then add 5.7 mL of EDMA, 28 mg of AIBN, blow nitrogen for 5 min, and seal the tube under vacuum , shaking in a constant temperature water bath at 60 °C for 24 h. After the polymerization reaction is completed, it is crushed, ground, and passed through a 120-mesh sieve. Put the obtained polymer in a Soxhlet extractor, elute with methanol solution containing 10 % (v / v) acetic acid until there is no characteristic absorption of phenol by ultraviolet detection (detection wavelength is 272 nm), and then soak in ethanol to remove residual acetic acid and methanol. After the treatment, the adsorbent was obtained by drying in a vacuum oven at 60 °C fo...

Abstract

The invention discloses a preparation method of an absorbent for effectively reducing phenol content in cigarette smoke. The preparation method comprises the following steps: preparing a phenol imprinting polymer by molecular imprinting technology and a bulk polymerization method, and obtaining the absorbent of which surface is porous and contains a plurality of holes matched with phenol molecules in structure and shape; and the absorbent has high selectivity to phenol. The absorbent is added into a ternary composite rod, the addition amount can be regulated as required, when the addition amount is 10 mg / cigarette, compared with a comparing sample, the reduction rate of phenol in cigarette smoke is 17.8%, and the relative reduction rate relative to tar is 11.8%; and when the addition amount is 20 mg / cigarette, the reduction rate of phenol in cigarette smoke is 28.7%, and the relative reduction rate relative to tar is 12.3%. The method is simple to operate, low in cost and convenient for a large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of cigarette material preparation, and in particular relates to a preparation method of an adsorbent capable of effectively reducing the phenol content in cigarette smoke. Background technique [0002] The smoke produced when cigarettes are burned contains carbon monoxide, phenol, nicotine and other harmful components. Among them, phenol directly enters the smoke when cigarettes are burned, which produces bad smell and is not conducive to human health. Therefore, it can effectively reduce the The content of phenol in flue gas is of great significance. [0003] In the prior art, there are records about the method of reducing phenol in cigarette smoke, but using molecular imprinting technology, the phenol imprinted polymer is prepared by bulk polymerization method, and added to the composite mouth rod as a phenol adsorbent in cigarette smoke Haven't seen reports yet. Contents of the invention [0004] The ...
