Embodiment 1
[0027] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL1.0mol / L potassium hydroxide solution dropwise, keep it under stirring for 1 hour, suction filter, wash with deionized water 3 times, and dry Dry in a box at 80°C for 12 hours, calcinate in a muffle furnace at 550°C for 2 hours, cool to room temperature naturally, then mix it with 170g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, take 40-60 mesh particles for later use.
[0028] The prepared additive was added to the cigarette filter at a rate of 40 mg / piece, and the filter without adding the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 10.8%.
Embodiment 2
[0030] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL 1.0mol / L potassium hydroxide solution dropwise, keep for 2 hours under stirring, suction filter, wash with deionized water 3 times, and dry Dry in a box at 100°C for 10 hours, calcinate in a muffle furnace at 500°C for 4 hours, cool to room temperature naturally, then mix it with 150g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, and take 40-60 mesh particles for later use.
[0031] The prepared additive was added to the cigarette filter at 30 mg / piece, and the filter without the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 9.6%.
Embodiment 3
[0033] Mix 0.005mol manganese nitrate, 0.05mol cerium nitrate and 100mL deionized water uniformly, add 160mL1.0mol / L potassium hydroxide solution dropwise, keep it under stirring for 1 hour, suction filter, wash with deionized water 3 times, and dry Dry in a box at 120°C for 8 hours, calcinate in a muffle furnace at 450°C for 3 hours, cool to room temperature naturally, then mix it with 180g chitosan, add 50mL 0.5mol / L potassium chloride solution, stir, Dry under a lamp, sieve to remove fine powder, take 40-60 mesh particles for later use.
[0034] The prepared additive was added to the cigarette filter at a rate of 20 mg / piece, and the filter without the filter rod additive of the present invention was used as a control. The smoke test results showed that the filter rod additive of the present invention can effectively reduce smoke compared with the control sample. The phenol content is 8.8%.
