Problems solved by technology

However, premature babies are prone to dysfunctions such as breathing, digestion, and temperature regulation, and even die soon after birth.
[0004] At present, there are very few purification technologies used to deal with nicotine pollution in cigarettes, but the pollution problem of cigarettes needs to be solved urgently, so it is very important to develop a new and efficient nicotine adsorbent

Abstract

The invention relates to a nicotine adsorbent and a preparation method thereof. The nicotine adsorbent is prepared by mixing mordenite raw powder and attapulgite powder in proportion and granulating the mixture. The preparation method comprises steps as follows: mixing of powdery materials: the mordenite raw powder and the attapulgite powder are uniformly added to a stirrer in the weight ratio being 4: (1-1.5) and stirred and mixed for 1.5-2.5 hours in the mixing stirrer; forming and granulation: a plurality of seeds are put in a granulator, the powdery materials are continuously added to the granulator, meanwhile, water mist is sprayed, the seeds grow to be adsorbent granules, and when the adsorbent granules reach predetermined specifications, the granules roll out of a discharge port of the granulator and conveyed to a vibrating sieving machine to be sieved; the water consumption in the whole forming and granulating processes doesn't exceed 35% of the weight of the powdery materials. The nicotine adsorbent has high nicotine adsorption capability, adsorption speed, saturated adsorbing capacity and adsorption rate and can realize thorough adsorption; the preparation method of the adsorbent is simple, convenient and low in production cost.

Description

technical field [0001] The invention relates to a nicotine adsorbent and a preparation method thereof, belonging to the technical field of air purification. Background technique [0002] Nicotine in cigarettes causes many health hazards, including increasing the risk of cardiovascular disease, cancer, and respiratory diseases in adults, aggravating asthma in children, and causing pneumonia and otitis media in children. Especially pregnant women and teenagers have unexpected harm. Moreover, harmful substances such as nicotine in cigarette smoke can also stimulate the brain, harden the blood vessels in the brain, and affect brain function. Studies have shown that the mental development of children who have been passively smoked for a long time is significantly worse than that of children who grew up in a non-smoking environment. [0003] If the mother inhales second-hand smoke for a long time during pregnancy, most of the harmful chemicals released when the tobacco burns can...
