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 volatile and semi-volatile organic compound is selected as toluene, 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 toluene (2.6 μg / μL), pipette 8 μL of the toluene solution and place it in the cracking tube of the thermal cracker, weigh Additive A, 328.9 mg (Additive B, 78.4 mg; Additive C, 65.2 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 50°C, and then the temperature is raised to the gasification tempera...

Abstract

The invention discloses a method for evaluating effects of filter tip additives for absorbing volatile and semi-volatile organic compounds in smoke, comprising steps of: performing GC-MS (gas chromatograph-mass spectrum) analysis according to a desorption amount of a target constituent at a certain temperature gradient after a filter tip additive absorbs the target volatile and semi-volatile organic compounds by a thermal cracker and the GC-MS method; and evaluating the absorbing effects of different filter tip additives to the volatile and semi-volatile organic compounds according to the desorption rate and desorption total amount of the target constituent at different temperatures. The operations of the method are simple; the analyzing and testing sensitivity is high; and a certain guiding value for developing and screening the filter tip additives is provided.

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 volatile and semi-volatile organic compounds in smoke. Background technique [0002] Volatile and semi-volatile organic compounds in cigarette smoke, such as benzene, toluene, pyridine, quinoline, styrene, nitrobenzene, etc., all have varying degrees of potential threats to human health to a certain extent. Adding additives with a specific pore structure to cigarette filters to selectively adsorb volatile and semi-volatile organic compounds is an effective method to reduce the release of these organic compounds in cigarette smoke. How to conveniently, quickly, accurately and efficiently evaluate the effect of different filter additives on the adsorption of volatile and semi-volatile organic compounds in smoke is of great significance for the screening and development of filter additives. Research on the device and me...
