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.

Highlights

Tobacco smoke is a complex aerosol containing of about 6000 components, which belong to different groups of chemical compounds (Rodgman and Perfetti, 2009)
The segmented zeolites were less efficient than those which were longitudinally applied. Both modes of zeolite application showed very good removing capacity in regard to the three investigated parameters and the only exception was in the case of zeolite Bl regarding nicotine
When zeolites were applied longitudinally, tobacco smoke made a better contact with the zeolite particles, the zeolite could fully activate its sorption capacity. The results of this experiment showed that both investigated zeolites, regardless of their types or mode of their application are very efficient in the reduction of hazardous substances in mainstream cigarette smoke

Summary

Introduction

Tobacco smoke is a complex aerosol containing of about 6000 components, which belong to different groups of chemical compounds (Rodgman and Perfetti, 2009). Of the many components of tobacco smoke, each has its own significance in terms of sensory properties and health aspects in regard to active and passive smokers (Fawky, 2004). Many constituents of tobacco smoke are harmful to human health, and some of them are even carcinogenic (Institute of medicine 2001; IARC, 2004). It has been estimated that there are 150 toxic chemical constituents in tobacco smoke (Rodgman and Green, 2003). Tar and nicotine can be found in the particulate phase of tobacco smoke, while CO is an integral part of the gas phase. The maximum permitted amounts of nicotine (1 mg/cig), tar and CO (10 mg/cig) in tobacco smoke are regulated by Tobacco Law of the Republic of Serbia (2019)
