Embodiment 1

[0030] 1. Accurately weigh 0.1 g carboxymethyl chitosan.

[0031] 2. Prepare 20ml of Fe with different concentrations 2+ Solution (regulate pH with antioxidant), under the uniform stirring of magnetic stirrer, add 0.1g carboxymethyl chitosan, stir and react for a certain period of time, stand still.

[0032] 3. Suction filter the solution. At this time, pipette 2mL of filtrate and dilute to 100mL volumetric flask, then pipette 1mL of diluted filtrate, add 2mL of 0.5% o-phenanthroline reagent, and dilute to 50mL. Used to determine the absorbance A of the sample.

[0033] 4. Continue to wash the sample with 1:1 acetone ethanol, and then wash with 95% ethanol until the sample does not contain SO 4 2- (Use barium nitrate to check whether there is a white precipitate in the filtrate), and finally wash with absolute ethanol, and vacuum-dry to constant weight.

[0034] Carboxymethyl chitosan Fe(II) complex was prepared by complexation reaction, and the effect of different prepara...

Embodiment 2

[0036] 1. Quantitatively analyze CO with external standard method, and formulate a standard curve for carbon monoxide.

[0037] 2. Dilute CO with a purity of 99.9% with air to obtain different concentration gradients. Under the same conditions, inject a certain amount of diluted CO with a known concentration to obtain the peak area of ​​CO in the gas sample;

[0038] 3. According to the response area of ​​different concentrations of CO, the standard curve of CO was established;

[0039] 4. When detecting the concentration of unknown CO in the mixed gas, calculate the concentration of CO in the component according to the response area of ​​the component and the standard curve of CO;

[0040] 5. Weigh a certain amount of adsorbent and put it into a sealed specific gravity bottle with a certain volume, and inject a certain amount of mixed gas of air and carbon monoxide with a syringe. After sealing again, under normal temperature and pressure, measure the content change of carbo...

Abstract

The invention discloses a cigarette filter tip which contains a carboxymethyl chitosan ferrous coordination compound, and a cigarette using the filter tip. In the invention, the carboxymethyl chitosan ferrous coordination compound is adopted in order to develop novel important technology to reduce the content of main smoke CO of the cigarette, which not only improves the safety of Chinese style cigarettes, but also helps us to reduce the harm caused by smoking on the human body.

Description

technical field [0001] The invention relates to the technical field of finished cigarettes, in particular to a cigarette filter tip and a cigarette using the filter tip. Background technique [0002] In the center of the burning area of ​​the cigarette when smoking, due to the insufficient supply of oxygen, it is easier to form CO, which is mixed in the smoke. About 30% of CO in smoke is produced by thermal decomposition of tobacco components, about 36% is produced by tobacco combustion, and at least 34% is produced by CO 2 Formed by reaction with carbon. CO is one of the main harmful components in cigarette smoke. When people smoke, the smoke enters the human trachea and lungs. Once inhaled, CO binds to hemoglobin, and its affinity with hemoglobin is much greater than that of O 2 (higher than O 2 200 times more), and than O 2 The dissociation with hemoglobin is much slower, which leads to a decrease in the oxygen transport capacity in the blood, hinders the oxygen utili...
