Abstract

Filtro de un artículo para fumar, que comprende un adsorbente de fenol del humo. El adsorbente de fenol incluye un material solido poroso que contiene un promotor de adsorcion en sus poros y, como opcion, en su superficie externa. En ausencia de dicho promotor de adsorcion, el material solido poroso contendría microporos y/o mesoporos. El promotor de adsorcion es una sustancia hidrofila orgánica y a la vez donante y aceptor de enlaces por puente de hidrogeno. El material solido poroso transmite el promotor de adsorcion en cantidad suficiente como para ampliar su adsorcion del fenol del humo. La solicitud también se refiere a un filtro similar donde el adsorbente comprende un material inorgánico particulado que porta un promotor de adsorcion sobre su superficie externa, y el promotor de adsorcion es un polietilenglicol o un polietilenglicol con extremos protegidos.Filter of an article for smoking, comprising a phenol adsorbent of smoke. The phenol adsorbent includes a porous solid material that contains an adsorption promoter in its pores and, as an option, on its outer surface. In the absence of said adsorption promoter, the porous solid material would contain micropores and / or mesopores. The adsorption promoter is an organic hydrophilic substance and at the same time a donor and acceptor of hydrogen bridge bonds. The porous solid material transmits the adsorption promoter in sufficient quantity to expand its adsorption of the smoke phenol. The application also refers to a similar filter where the adsorbent comprises a particulate inorganic material that carries an adsorption promoter on its outer surface, and the adsorption promoter is a polyethylene glycol or a polyethylene glycol with protected ends.
