Removal of some amine and cyanic compounds in cigarette smoke via synthesized zeolite X (ZX) from micro silica

Silica is a compound found in some plants and one of the most important materials in chemical industrial and adsorption processes. for this study, micro silica was extracted from Equisetum arvense plant in North of Iran and purified from in electric furnace at 1300°C for 4 hours. SEM measurements determined a particle size of micro silica of 1-1.5 micrometer. Zeolite NaX was synthesized from micro silica and sodium alumina solutions by hydrothermal method . The premixed molar oxide ratio of this zeolite was 2SiO2:Al2O3:4Na2O:120H2O. The XRD (GBC MMA) pattern has been used for characterizing of synthetic zeolite. The XRD pattern of synthetic zeolite are matched to the zeolite X (Gramlich et al., 1971). This shown the synthetic zeolite is NaX type.The cigarettes used in this study were prepared by adding 25 mg ZX to each filter tip of the commercial cigarettes.
