Abstract

Filtration is one way of purification of tobacco smoke. The aim of this study was to examine the potential filtration effects of zeolites Y and ZSM-5, with different degree of crystallinity and in two modes of application (as a segment or as a powder added longitudinally with the filter fibers). Zeolites were added in the quantity of 60 mg. Degree of filter efficiency and sorption capacity has been determined in regard to several hazardous constituents of mainstream tobacco smoke such as: tar, carbon monoxide and nicotine. Composition of mainstream tobacco smoke was determined by using standard ISO methods.  Experimental results showed that both, the type and the mode of the zeolite application affected the efficiency of smoke filtration. Zeolite Y, which was longitudinally applied to the filter, is shown to be the most effective. It was found 58.82% reduction of nicotine, 66.86% of tar and 86.24% of CO. During segmental application of zeolites, the blocking effect was observed.
