Embodiment 1

[0020] The strongly acidic cation exchange resin 001*7 is packed in absolute ethanol first, soaked for 2 hours and then rinsed with absolute ethanol to remove impurities. Double the bed volume of water, 2 times the bed volume of 4% hydrochloric acid solution, 10-12 bed volumes of water treatment resin, wash with water until neutral, and then use 5-10 times the bed volume of 0.8M CuSO 4 , Fe 2 (SO 4 ) 3 , Ni(NO 3 ) 2 The resin was treated with an aqueous solution, washed with water until no metal ions flowed out, filtered, and vacuum-dried at 50°C for 30 minutes to obtain a series of metal complex materials exchanged with 001*7.

[0021] The above materials are applied to cigarettes in the form of binary composite filter rods, with an additive amount of 30mg / cig (sticks), marked as cigarette sample 2, and cigarettes without any filter modification materials added as control samples, the cigarettes used before the test Equilibrate for 48 hours under the conditions of temper...

Embodiment 2

[0026] The macroporous strongly acidic macroporous adsorption resin D072 is first packed with ethanol, soaked for 2 hours and then rinsed with ethanol to remove impurities, and then washed with 2 times the bed volume of 4% sodium hydroxide solution, 5-6 times the bed volume water, 2 times the bed volume of 4% hydrochloric acid solution, 10-12 bed volumes of water treatment resin, washed with water to neutrality, and then used 5-10 times the bed volume of 0.1M CuSO 4 , ZnSO 4 , MnSO 4、 Treat the resin with an aqueous solution, wash it with water until no metal ions flow out, and dry it in vacuum at 50°C for 30 minutes to obtain a series of metal complex materials exchanged with D072.

[0027] Apply the above-mentioned materials to cigarettes in the form of binary composite filter rods, the addition amount is 30 mg / cig (sticks), and the cigarettes without any filter modification materials are used as control samples. )°C and relative humidity (60±2)% for 48 hours, and then sor...

Abstract

The invention relates to a metal complexing material and a preparation method thereof, and application of the metal complexing material to cigarettes. The invention is characterized in that: the complexing material is obtained by complexing a porous carrier with large specific surface area, such as ion exchange resin, ion exchange fibers, macroporous adsorption resin and the like, and different metal ions, and is applied to the cigarettes in a form of a binary composite filter stick; 10 to 40mg of complexing material is added into each cigarette, so that hydrogen cyanide (HCN) in mainstream smoke can be selectively reduced by over 25 percent; meanwhile, the complexing material does not have negative effects on the sensory quality of the cigarettes. The porous carrier in the material has large specific surface area, so smoke can be effectively contacted with the functional group of the material when passing through the material; meanwhile, the metal ions on the surface can be subjectedto complexing reaction with the HCN, so that the HCN in the smoke of the cigarettes is selectively removed.

Description

technical field [0001] The invention relates to a metal complex material for selectively reducing HCN in mainstream smoke of cigarettes, a preparation method thereof and application in cigarettes. Applying the material to cigarette filter rods can effectively reduce the release of hydrocyanic acid in mainstream smoke without negatively affecting the sensory quality of cigarettes. Background technique [0002] Hydrocyanic acid (HCN) is a highly volatile and highly toxic substance, and the poisoning effect is mainly through CN - occur. Hydrocyanic acid in cigarettes mainly comes from the oxidative decomposition of nitrates and nitrogen-containing compounds in tobacco during the burning and smoking process, and its release amount is about 30-300??g / cig. Quickly enter the body and cause harm to human health. Therefore, the development of materials that can effectively reduce the release of hydrocyanic acid in mainstream cigarette smoke is of great significance for improving t...
