    摘要： An activated carbon-containing sorbent is capable of selectively removing one or more selected gaseous components from a gas. The activated carbon-containing sorbent can be incorporated in a smoking article to remove one or more selected components from mainstream smoke. The activated carbon-containing sorbent can be a composite including one or more molecular sieve materials. Methods of making the activated carbon-containing sorbent, cigarette filters and smoking articles including the activated carbon-containing sorbent, as well as methods for smoking a cigarette comprising the activated carbon-containing sorbent, are provided.

    摘要： A filter such as an air having a reagent which chemically reacts with and removes a gaseous component of an air stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel). The reagent can be contained in a space in the filter or incorporated in one or more filter elements. The reagent can be part of or coated on paper such as filter paper or incorporated in non-paper filter elements formed from fibrous materials such as cellulose acetate or polypropylene fibers. Other preferred reagents include aminoethylaminopropylsilyl silica gel (AEAPS) and aminoethylaminoethylaminopropylsilyl silica gel (AEAEAPS).

    摘要翻译： 一种过滤器，例如空气，具有与空气流的气体成分发生化学反应并除去气态组分的试剂。 该试剂含有共价结合到过滤器中的非挥发性无机底物的官能团。 过滤器可以除去气体组分如醛。 优选的官能团是与硅胶共价结合的3-氨基丙基甲硅烷基（APS硅胶）。 试剂可以包含在过滤器的空间中或者被包含在一个或多个过滤元件中。 试剂可以是诸如滤纸的纸上的一部分或涂布在纸上，或者被引入由诸如醋酸纤维素或聚丙烯纤维的纤维材料形成的非纸过滤元件中。 其他优选的试剂包括氨基乙基氨基丙基甲硅烷基硅胶（AEAPS）和氨基乙基氨基乙基氨丙基硅烷基硅胶（AEAEAPS）。

    摘要： A cigarette filter having a reagent which chemically reacts with and removes a gaseous component of a smoke stream. The reagent contains functional groups covalently bonded to a non-volatile inorganic substrate which is incorporated in the filter. The filter can remove gaseous components such as aldehydes from tobacco smoke. Preferred functional groups are 3-aminopropylsilyl groups covalently bonded to silica gel (APS silica gel). The reagent can be contained in a space in the filter or incorporated in one or more filter elements such as tipping paper, shaped paper insert, mouthpiece plug, solid filter element, or free-flow filter element. The reagent can be part of or coated on paper such as tipping or filter paper or incorporated in non-paper filter elements formed from fibrous materials such as cellulose acetate or polypropylene fibers. Other preferred reagents include aminoethylaminopropylsilyl (AEAPS) silica gel and aminoethylaminoethylaminopropylsilyl (AEAEAPS) silica gel.
