NOVELTY - This new utility model belongs to citiggrate filter stick production technique area, specifically relates to one added with high efficient adsorption capacity of the oxidation graphite alkene-mesoporous silicon dioxide composite material is citiggrate filter rod. The filter stick is binary composite filter stick, comprising common vinegar fibre filter element, granule acetate fiber filter element and in turn covered on two section filter element out the outside forming paper and tipping paper. The application of providing citiggrate filter stick, at the same time combination of mesoporous silicon dioxide and oxidation graphene two absorbing material is of excellent performance, wherein addition quantity compare at least the following information, may be corresponding aldehyde ketone volatility promote cancer molecule, phenol equal harmful material by high efficient adsorption, and the composite material green environmental protection, without additional toxicity, at the same time the preparation method is simple, the raw material is easy to obtain, easy to produce on scale production and production cost is low, so tar-reducing and harm area in reducing citiggrate with wide application prospect.
