Experiments on Application of Palygorskite Adsorbent into Cigarette Filter

Experiments on application of palygorskite adsorbent into cigarette filter were conducted in order to search for an adsorbent capable of selectively removing harmful compounds in cigarette smoke. The 3% glycerin suspension solution of palygorskite was applied to bloomed acetate tow and the filter rod containing about 1.5 milligrams of palygorskite adsorbent per 120 millimeter length were made and then attached to the tested cigarettes. The smoke analysis and sensory evaluation of the tested cigarettes indicated that, comparing with the control, the tar and carbon monoxide deliveries were decreased by 1.4mg and 1.1mg per cigarette, respectively. However, nicotine delivery and smoking quality of the cigarettes were not affected.
