【摘要】 比较了分别添加碳纳米管（CNTs）、活性炭、NaCl、MgSO₄、Al（OH）₃的卷烟过滤嘴对烟气中总粒相物的去除效果,初步研究了过滤嘴中CNTs的处理程度、填充数量对去除效果的影响及作用。结果表明,CNTs对烟气中总粒相物的去除能力优于其它材料,并且浅处理（用浓硝酸浸泡5 min）的CNTs的去除能力优于深处理（用浓硝酸煮沸40 min）的CNTs,每支烟中浅处理的CNTs添加量为20～30 mg时效果较好。更多还原

【Abstract】 The removal of the total particulate matter from cigarette smoke by the filter tips filled with carbon nanotubes（CNTs）, active carbon, NaCl, MgSO₄ and Al（OH）₃ has been compared. The results show that the removal efficiency of light purified CNTs（immersed in nitric acid for 5 minutes）is higher than that of other materials, even higher than that of heavy purified CNTs（boiled in nitric acid for 40 minutes）. The optimal mass of the light purified CNTs for one cigarette is 20～30 mg.更多还原
