This invention refers to a method of withholding noxious compounds contained in cigarette smoke (NO, NOx, carcinogenic nitrosocompounds, free radicals, H2O2, CO, aldehydes, and trace elements) which were up to today insufficiently retained by conventional cigarette filters. The method described specifically refers to the enrichment of common convention filters with biological substances of the metal ions (Fe2+, Cu2+, Mg2+) complexed with porphirin ring as well as Fe2+ ions stereospecifically bound to protein molecules, either separately or in combinations. The enrichment of these conventional filters with the abovementioned biological substances alters neither the physical properties of the cigarette smoke (odor, taste and appearance) nor the physical properties of the filter itself.
Procédé d'élimination des composés nocifs présents dans la fumée de la cigarette (NO, NOx, composés nitreux cancérogènes, radicaux libres, H¿2?O¿2?, CO, aldéhydes et oligo-éléments), composés que les filtres de cigarette traditionnels ne pouvaient jusqu'à présent éliminer suffisamment. Ce procédé consiste plus spécialement à enrichir les filtres traditionnels avec des substances biologiques des ions métalliques Fe?2+¿, Cu?2+¿, Mg?2+¿, complexés avec un cycle porphyrinique, ainsi que des ions Fe?2+¿ liés de manière stéréospécifique à des molécules protéiques, et ce individuellement ou en combinaison. L'enrichissement des ces filtres traditionnels en substances biologiques du type précité ne modifie ni les caractéristiques physiques de la fumée de la cigarette (odeur, goût et aspect) ni celles du filtre proprement dit.
