Abstract

The invention discloses an additive for reducing ammonia release quantity in cigarette smoke and a preparation method thereof. Alkaline earth metal chlorides are dispersedly loaded on meso-porous silicon; the load is less than 40% of total weight; the aperture of meso-porous silicon is 2-50nm; the specific surface area is not smaller than 300m<2> / g; and the particle size is 40-80 meshes. The method comprises the steps of weighing alkaline earth metal compound to dissolve into a proper amount of deionized water; agitating to form uniform solution; adding the meso-porous silicon to evenly agitate, standing for 12 hours at room temperature, putting into an oven to dry, and cooling to room temperature to obtain the additive. Compared with the prior art, the preparation method is simple in process, low in cost, and significant in ammonia-reducing effect, and can achieve industrial application; and a filter rod with the additive added therein disclosed by the invention is applied to the cigarette. From the result of experiments, the release quantity of ammonia in the cigarette smoke can be effectively reduced; the gas-phase ammonia is greatly reduced by the functional meso-porous silicon material; and particle-phase ammonia is also reduced to a different extent.

Description

technical field [0001] The invention relates to a method for selectively reducing NH in cigarette mainstream smoke 3 release amount of adsorbent. Background technique [0002] With the progress of society, people pay more and more attention to their own health. As a signatory of the Framework Convention on Tobacco Control, China will further increase the efforts to reduce the harm and burn of cigarettes, which is related to the survival and development of my country's tobacco industry. According to statistics from the International Tobacco Research Organization, as of 2011, more than 5,000 components have been identified in cigarette smoke, 99.4% of which are harmless to humans. In 2009, the Zhengzhou Tobacco Research Institute led a study on the cigarette smoke hazard index of Chinese-style cigarettes. Among the 29 harmful components in mainstream cigarette smoke, 7 representative components were selected as cigarette hazard evaluation indicators. Ammonia is one of them. ...
