摘要

A method of making a first tobacco smoke filter segment is disclosed. The method comprises the steps of providing one or more than one copper-containing porphyrin; producing a mixture of cellulose fiber, sodium sulfate, sodium carbonate, chitin and the copper-containing porphyrin; heating the mixture for a sufficient time at one or more than one temperature sufficient to covalently link the copper- containing porphyrin to the cellulose fiber; and (d) forming the cellulose fiber with covalently bound, copper-containing porphyrin into the first tobacco smoke filter segment. A smokable device comprising filter segment is also disclosed.
