Abstract

The invention relates to a filter for a smoking article, said filter comprising an adsorbent of phenol from smoke, said adsorbent comprising a porous solid material bearing an adsorption promoter in its pores and, optionally, on its outer surface; wherein said porous solid material, in the absence of said adsorption promoter, would contain micropores and/or mesopores; and wherein said adsorption promoter is a hydrophilic organic substance and both a hydrogen bond donor and acceptor, and is borne by said porous solid material in an amount sufficient to enhance the adsorption of phenol from smoke by the porous solid material. The invention also relates to a similar filter wherein the adsorbent comprises a particulate inorganic material bearing an adsorption promoter on its outer surface, wherein the adsorption promoter is a polyethylene glycol or end-capped polyethylene glycol.
