Embodiment Construction

[0022] The present invention is described in further detail below, but the following examples are illustrative, not restrictive, and cannot limit the protection scope of the present invention with this.

[0023] Evaluation example: the target phenolic compound is selected as phenol, and the filter additives to be evaluated are powdered microporous molecular sieve A, mesoporous molecular sieve B, and hierarchical porous molecular sieve C.

[0024] (1) Preparation: prepare an ethanol solution of phenol (2.5 μg / μL), pipette 3 μL of the phenol solution and place it in the cracking tube of a thermal cracker, weigh Additive A, 318.2 mg (Additive B, 86.2 mg; Additive C, 64.3 mg) the sample adsorption tube of the thermal cracker is filled up, and the empty sample adsorption tube is used as a blank;

[0025] (2) Gasification and adsorption: The initial temperature of the cracking tube is 80°C, keep it warm for 1min to remove the sample solvent, then raise the temperature to the gasific...

Abstract

The invention discloses a method for evaluating the adsorption effect of a filter tip additive on phenolic compounds in smoke, wherein a pyrolysis device and a gas chromatography-mass spectrometry combined method (GC-MS) are used, and the method comprises the following steps: allowing a filter tip additive to adsorb a target phenolic compound, allowing the target component to be desorbed under a certain temperature gradient, analyzing the amount of the desorbed component by GC-MS, and evaluating the adsorption effect of different filter tip additives on phenolic compounds by the desorption rates and the total desorption amounts of the target component at different temperatures. The method has simple and rapid operations, high sensitivity of analysis and testing, and has certain guiding value for the development and screening of filter tip additives.

Description

technical field [0001] The invention relates to the field of tobacco, in particular to a method for evaluating the effect of a filter tip additive on absorbing phenolic compounds in smoke. Background technique [0002] Phenolic compounds are an important class of substances in cigarette smoke. Phenolic compounds themselves are not carcinogenic, but studies have shown that they have obvious cancer-promoting effects. Adding additives with a specific pore structure to cigarette filters to selectively adsorb phenolic compounds in smoke can reduce the release of phenolic compounds in smoke, thereby reducing the harm of cigarette products to consumers. Extensive research has been carried out at home and abroad on the screening and development of filter additives for adsorbing phenolic compounds in smoke. The screening and development of filter additives is of great significance, but also faces many challenges. At present, there are few research reports on the evaluation methods ...
