• hydrogen cyanide
• formaldehyde
• acetaldehyde
• selective adsorption
• ion exchange resin

This study used several ion-exchange resins and showed that CR11 and AMP16OH have highly selective area and are efficient adsorbents for formaldehyde, acetaldehyde and HCN in the smoke generated from Ky3R4F reference cigarette smoke. The substantial adsorption of HCN (>95%) and formaldehyde (>50%) was also observed. The decrease in these compounds was greater than that from using an activated carbon and synthesis zeolite. The results also demonstrated that chemisorption was an effective mechanism for the adsorption of certain vapor phase constituents from cigarette mainstream smoke. The results may be helpful in designing selective filter and understanding the retention mechanism of mainstream smoke compounds in previous studies and practical filter materials.
