Abstract

Un filtro de cigarrillo que posee un reactivo que reacciona químicamente con y elimina un componente gaseoso de una corriente de humo. El reactivo contiene grupos funcionales covalentemente ligados a un substrato inorgánico no volátil que se incorpora en el filtro. El filtro puede remover componentes gaseosos tal como aldehidos del humo del tabaco. Los grupos funcionales preferidos son grupos 3-aminopropilsililo covalentemente ligados a gel de sílice ( gel de sílice APS). El reactivo puede estar contenido en un espacio en el filtro o incorporado en uno o más elementos de fitro tal como papel de boquilla, inserción de papel configurado, tapón de boquilla, elemento de filtro sólido o elemento de filtro de flujo libre. El reactivo puede ser parte de papel o recubrir papel tal como papel de boquilla o filtro o incorporarse en elementos de filtro que no son de papel formados a partir de materiales fibrosos tales como acetato de celulosa o fibras de polipropileno. Otros reactivos preferidos incluyen gel de sílice de aminoetilaminopropilsililo (AEAPS) y gel de sílice de aminoetilaminoetilaminopropilsililo (AEAEAPS).
