Abstract: In order to reduce benzoapyrene in cigarette smoke effectively,a filter adsorbent of netty macromolecular porous material was prepared and researched.The results of material test,smoke analyzing and sensory evaluating showed that:1) the prepared material was of porous cylindrical particle with particle size of 0.1-10 μm,particle thickness of 1-3 μm and pore diameter of 2-3nm;it was a kind of nanosized mesoporous netty macromolecular material and possessed the character of a molecular screen;2) the material had higher benzoapyrene adsorbility,it reduced much more benzoapyrene(over 35%) than tar(10%) in the contrast test;while it had little effect on moisture content,nicotine,and its effect on smoking quality was not significant;3) the raw material for making this adsorbent was readily available and the synthesizing process was simple,the pore size and hydrophilicity were adjustable,the technology for filter making was simple and filter quality was stable,the cost(100 yuan/kg) was easy to be controlled,and the prospect of its application was good.
