Abstract:

The study was carried out to analyse the susceptibility of textile polymers, polyamide and polypropylene, used in the manufacture of floor coverings, to the sorption of nicotine from environmental tobacco smoke (ETS) polluted air and nicotine itself. Polypropylene fibres were modified by means of titanium dioxide doped with nanosilver particles (TiO2/Ag). The decomposition kinetics of nicotine adsorbed by polypropylene fibres and the catalytic effect of TiO2/Ag on the decomposition of nicotine were investigated. Having analysed the concentrations of nicotine adsorbed from ETS by polyamide fibres and polypropylene fibres, it was found that the latter demonstrate a much stronger sorption of nicotine. It was also observed that the nanomodifier TiO2/Ag substantially accelerates the photocatalytic decomposition of nicotine adsorbed by polypropylene fibres.
