Abstract

The invention discloses an additive for selectively adsorbing crotonaldehyde and phenol as well as a preparation method and application of the additive. CuAPO-5 is synthesized by adopting a hydrothermal method and taking triethylamine as a template agent, copper nitrate as a copper source, pseudo-boehmite as an aluminum source and phosphoric acid as a phosphorus source. The test result of a cigarette additive test shows that the additive obviously adsorbs tobacco specific harmful gases such as phenol, crotonaldehyde and tar, especially phenol. The additive has the advantages of good adsorptioneffect, strong plasticity, safety, innocuity, low price and the like, and has a good application value.

Description

technical field [0001] The invention relates to an additive for selectively adsorbing crotonaldehyde and phenol, a preparation method and application thereof, and belongs to the field of functional materials for reducing tar and detoxification of cigarettes. Background technique [0002] Cigarette smoke is a mixture of extremely complex components produced by high-temperature combustion, cracking, distillation and other processes during the smoking process of tobacco products. As we all know, smoking is harmful to health. Since the 1950s, tobacco tar reduction and harm reduction have been the focus and hotspot of international tobacco research. In 1954, Cooper et al. first discovered the carcinogenic component, benzo[a]pyrene, from cigarette smoke. Subsequently, there have been more and more studies on harmful components in cigarette smoke. From the list of 43 harmful ingredients published by Hoffmann in 1990 to the list of 46 harmful ingredients released by the Canadian g...
