ABSTRACT:
A surface-modified adsorbent comprises a reagent on a porous carrier. Preferred porous carriers are adsorbent carbons such as activated carbon, silica gels, aluminas, polyester resins, zeolites or zeolite-like materials, and mixtures thereof. Preferred reagents are 2-hydroxymethylpiperidine (2-HMP) or a 2-HMP analogue. Surface modified adsorbents can be incorporated into cigarettes, preferably in an amount effective to reduce the concentration of one or more constituents of cigarette smoke.
