Abstract

FILTRO PARA FUMAçA DE TABACO, MéTODOS PARA FILTRAçãO DE FUMAçA, PARA FILTRAçãO DE FLUXO DE FLUIDO E PARA REMOVER PRODUTOS DE PIRóLISE DE MATERIAIS DE CIGARRO A PARTIR DA FUMAçA DE CIGARRO, MEIO PARA FILTRAçãO DE FUMAçA DE TABACO, E, MéTODOS PARA MANUFATURAR UM FILTRO E PARA REMOVER UM COMPONENTE GASOSO DE UMA MISTURA DE GáS. Um filtro de artigo de fumar, tendo uma resina porosa com uma elevada relação de área de superfície para massa, compreendendo um derivado de quitosana. Formas de realização preferidas incluem quitosana reticulada com glutaraldeído e quitosana reticulada com glioxal. O derivado de quitosana fornece a filtração seletiva de fumaça de cigano, particularmente para a remoção de aldeídos, cianeto de hidrogênio, metais pesados e carbonilas.TOBACCO SMOKE FILTER, METHODS FOR SMOKE FILTRATION, FLUID FLOW FILTERING AND TO REMOVE CIRCULAR MATERIALS PYROLYSIS PRODUCTS, TOUCH AND FILTRATE SMOKE FILTERING MEANS, AND TO REMOVE A GAS COMPONENT FROM A GAS MIX. A smoking article filter having a porous resin with a high surface area to mass ratio comprising a chitosan derivative. Preferred embodiments include glutaraldehyde cross-linked chitosan and glyoxal cross-linked chitosan. Chitosan derivative provides selective filtration of gypsy smoke, particularly for the removal of aldehydes, hydrogen cyanide, heavy metals and carbonyls.
