Embodiment 1

[0102] The MOF(Fe) material was synthesized by hydrothermal method, and 5.7714g Fe(NO 3 ) 3 9H 2 Dissolve O in 72ml of deionized water, add 5.71ml of 5M hydrofluoric acid, stir well to dissolve it, weigh 1.98g of 1,3,5-trimellitic acid and add it to a 100ml reaction vessel with a Teflon reaction liner In the kettle, pour the dissolved ferric nitrate solution into it and seal it. The reaction kettle was heated in an oven at 150° C. for 16 hours. After the reaction was completed, it was naturally cooled to room temperature, and centrifuged to obtain a light orange solid. Disperse 1 g of the light orange solid obtained above into 300 ml of deionized water, heat it in a water bath to 80 ° C, and perform magnetic stirring at the same time, cool to room temperature after 4 hours and centrifuge; then mix the sample with 100 ml of absolute ethanol and heat it in a water bath to 60 °C ℃ while magnetically stirring for 2 hours, after the solution was cooled to room temperature, it w...

[0104] The MOF(Fe) material was synthesized by hydrothermal method, and 5.7714g Fe(NO 3 ) 3 9H 2Dissolve O in 65ml of deionized water, add 4.30ml of 5M hydrofluoric acid, stir well to dissolve it, weigh 1.52g of 1,3,5-trimellitic acid and add it to a 100ml reaction vessel with a Teflon reaction liner In the kettle, pour the dissolved ferric nitrate solution into it and seal it. The reaction kettle was heated in an oven at 140° C. for 12 hours. After the reaction was completed, it was naturally cooled to room temperature, and centrifuged to obtain a light orange solid. Disperse 1 g of the light orange solid obtained above into 200 ml of deionized water, heat in a water bath to 70 ° C, and perform magnetic stirring at the same time, cool to room temperature after 3 hours and centrifuge; then mix the sample with 60 ml of absolute ethanol and heat in a water bath to 50 ℃ while magnetically stirring for 2 hours, after the solution was cooled to room temperature, it was centrifu...

Embodiment 3

[0106] The MOF(Fe) material was synthesized by hydrothermal method, and 5.7714g Fe(NO 3 ) 3 9H 2 Dissolve O in 77ml of deionized water, add 11.42ml of 5M hydrofluoric acid, stir well to dissolve it, weigh 2.39g of 1,3,5-trimellitic acid and add it to 100ml of Teflon reaction liner for reaction In the kettle, pour the dissolved ferric nitrate solution into it and seal it. The reaction kettle was heated in an oven at 160° C. for 24 hours. After the reaction was completed, it was naturally cooled to room temperature, and centrifuged to obtain a light orange solid. Disperse 1 g of the light orange solid obtained above into 400 ml of deionized water, heat in a water bath to 80 ° C, and perform magnetic stirring at the same time, cool to room temperature after 5 hours and centrifuge; then mix the sample with 100 ml of absolute ethanol in a water bath and heat to 70 ℃ while magnetically stirring for 4 hours, after the solution was cooled to room temperature, it was centrifuged an...

Abstract

The invention provides a preparation method of a metal organic framework material. The metal organic framework material is synthesized by virtue of a hydrothermal method or a heating reflux method and is a metal organic framework MOF(Fe) material. The invention also discloses a cigarette filter tip added with the metal organic framework MOF(Fe) material. According to the preparation method and application of the metal organic framework material, by adding the metal organic framework MOF(Fe) material into the cigarette filter tip, the contents of harmful ingredients such as ammonia and benzo[a]pyrene in cigarette mainstream smoke can be effectively decreased; the environmental friendliness is achieved and the safety to a human body after the material is added into the cigarette is ensured. Meanwhile, the metal organic framework MOF(Fe) material has super-strong adsorption capacity to organic dye pollutants and is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the field of tobacco harm reduction and the field of environment, and relates to the preparation and application of a metal organic framework material, in particular to the preparation of a metal organic framework MOF (Fe) material and its effect on harmful components or organic dyes in cigarette mainstream smoke Applications in Pollutant Adsorption. Background technique [0002] Improving the safety of cigarettes and reducing the release of harmful components in cigarette smoke is the development direction of international cigarette technology, and it is also an inevitable demand for the development of Chinese-style cigarettes. Seven kinds of harmful components in cigarettes (CO, NH 3 , HCN, NNK, B[a]P, crotonaldehyde, and phenol) can effectively characterize the biohazardousness of mainstream cigarette smoke, and selectively reducing the seven harmful components is the technical key to further reducing tar and harm. Researc...
