Abstract

The invention discloses a filter tip for adsorbing benzopyrene in cigarette smoke. The filter tip belongs to a binary compound filter tip and comprises a graphitized multi-walled carbon nanotube segment at the end close to tobacco shred and a cellulose acetate segment at the end close to the tip, wherein the graphitized multi-walled carbon nanotube segment at the end close to the tobacco shred is formed by graphitized multi-walled carbon nanotubes and Lyocell fiber; according to the filter material of the filter tip, the graphitized multi-walled carbon nanotubes are used as the adsorbent, and due to the fact that the graphitized multi-walled carbon nanotubes have a unique porous and hollow structure, larger specific surface area and multiple interaction among pollutants, the filter tip has excellent adsorption performance on the benzopyrene in the cigarette smoke and can further adsorb parts of heavy metals such as Pb and Cd in the cigarette smoke at the same time.

Description

technical field [0001] The invention belongs to the field of cigarette materials and relates to a filter for cigarettes, in particular to a filter for selectively absorbing benzopyrene and phenol in cigarette smoke. Background technique [0002] At present, the tobacco industry is facing multiple pressures from the World Health Organization and the [Framework Treaty on Tobacco Control]. On the other hand, with the continuous improvement of living standards and quality of life, the contradiction between smoking and health has become increasingly prominent, and the requirements for cigarette safety Higher and higher, improving the safety of cigarettes and reducing the release of harmful components in cigarette smoke is the development direction of international cigarette technology, and it is also an inevitable demand for the development of Chinese-style cigarettes. [0003] The International Agency for Research on Cancer (IARC) conducted animal carcinogenicity tests on fused-...
