Embodiment 1~6
[0007] The preparation of embodiment 1~6 additional adsorbent
[0008] The low-silicon-aluminum-ratio zeolite and high-silicon-aluminum ratio molecular sieve are mixed according to a certain weight ratio, and then ground into a fine powder larger than 300 meshes. The specific compositions of adsorbents 1, 2, 3, 4, 5, and 6 are shown in Table 1.

Embodiment 7~16
[0010] The preparation of embodiment 7~16 additional adsorbent polypropylene tow
[0011] The molecular sieve adsorbent prepared by the methods of Examples 1 to 6 was mixed with polypropylene powder or granules for commercially available cigarette filter rods in different proportions, and then fully miscible, followed by wire drawing, to prepare Example 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 polypropylene tow.

Embodiment 17
[0013] The performance of the polypropylene fiber tow of embodiment 17 additional adsorbents
[0014] The tows of Examples 7-16 are drawn to make a polypropylene fiber filter rod containing an adsorbent, and the filter rod is used to make a cigarette filter.
[0015] Using the cigarettes made of the above filters, the conventional methods for analyzing various components of cigarette smoke were used to analyze the components of cigarette smoke passing through the additive polypropylene fiber filter, and the results are listed in Table 3.
