Abstract
A SMOKING ARTICLE FILTER HAVING A POROUS RESIN WITH A HIGH SURFACE AREA TO MASS RATIO COMPRISED OF A CHITOSAN DERIVATIVE. PREFERRED EMBODIMENTS INCLUDE CHITOSAN CROSS- LINKED WITH GLUTARALDEHYDE AND CHITOSAN CROSS-LINKED WITH GLYOXAL. THE CHITOSAN DERIVATIVE PROVIDES FOR THE SELECTIVE FILTRATION OF CIGARETTE SMOKE, PARTICULARLY FOR THE REMOVAL OF ALDEHYDES, HYDROGEN CYANIDE, HEAVY METALS AND CARBONYLS.
