preparation example Construction
[0043] Filtration articles may be prepared according to known methods for preparing similar products.
[0044] According to the required shape, filter products can be made into different shapes, such as cylindrical, cylindrical, ring-shaped, granular, etc., for example, formed into the desired shape by the usual method, such as cigarette filters, gas mask filter cores, etc. . The hydrated aluminosilicate can also be directly used in cigarettes. For example, the hydrated aluminosilicate has a size of more than 325 mesh, and is evenly added to the shredded tobacco at a ratio of 0.01% to 5%, so that the shredded tobacco can be used before or during combustion. In itself becomes a filter product.
[0045] The filtering product of the present invention can be used for removing gas, especially harmful components in cigarette smoke, and achieves satisfactory effects, especially good for removing tobacco-specific nitrosamines, condensed ring aromatic hydrocarbons, free radicals and t...

[0049] 1. Three polycyclic aromatic hydrocarbons (Polycyclic Aromatic Hydrocarbons, PAHs) in cigarette smoke (benzo[a]pyrene (abbreviated as "b[a]p"), benzo[a]anthracene (abbreviated as "b[a]A" )and (hereinafter referred to as "CH")) Determination method
[0050] 1. Reagents and Instruments
[0051] Cyclohexane, n-hexane, anhydrous ether (all chromatographically pure); benzo[a]pyrene, benzo[a]anthracene, Standard sample (Fluka Company, USA); 9-phenylanthracene standard sample (Fluka); stoppered Erlenmeyer flask, concentration bottle; silica gel solid phase extraction column; rotary evaporator; HP6890-5973MSD color-mass spectrometer; Capillary chromatographic column HP-5MS 30m×0.25mm×0.25μm, JJ-3A smoking machine (made in China, Zhengzhou Tobacco Research Institute).
[0052] 2. Collection and pretreatment of total particulate matter in flue gas
[0053]Before the test, the cigarettes used were balanced for 48 hours under the conditions of (...
Embodiment 1
[0083] According to the ratio of 2 mg hydrated aluminosilicate / filter tip, fully mix the hydrated aluminosilicate and ordinary granular activated carbon according to the weight ratio of filter material: activated carbon = 2:15, and then filter the hydrated aluminosilicate according to the cigarette filter production requirements Activated carbon as the material was uniformly dispersed in 700 mg of cellulose acetate used to manufacture the filter to prepare a cigarette filter (composite tip rod, diameter: 7.8 mm, length: 24 mm). The composition of hydrated aluminosilicate is:
[0084] CaO 1.0%
[0085] MgO 2.0%
[0086] Fe 2 o 3 3.0%
[0087] K 2 O 0.5%
[0088] Al 2 o 3 13.0%
[0089] SiO 2 75%
[0090] The hydrated aluminosilicate is in the form of powder, all of which pass through a 20-mesh sieve.
[0091] Remove the filter tip from the commercially available Zhongnanhai brand cigarette of Beijing Cigarette Factory, plug the cigarette filter tip prepared a...
